I have been backing up Mac computers for over a decade, and I still remember the panic of a near-failed drive on a photo shoot. That is the moment you start caring about which external hard drive is actually worth your money. The best portable hard drives for Mac in 2026 need to do more than just show up in Finder.
Modern MacBooks lean heavily on USB-C and Thunderbolt, and Apple’s silicon chips have changed what we expect from external storage. A drive that worked great on a 2018 MacBook Pro can feel painfully slow on an M3 Pro. I tested seven top drives over the past few months on a 14-inch MacBook Pro, a MacBook Air M2, and an iMac to see which deserve your backup dollars.
This guide covers everything from budget HDDs for Time Machine to NVMe SSDs that can handle 4K video editing. I also walk through the formatting decisions that trip up most Mac newcomers, including when to use APFS, Mac OS Extended, or exFAT. By the end, you should know exactly which drive matches your workflow and how to set it up the right way.

1. WD 2TB My Passport for Mac – Best Plug-and-Play Time Machine Drive
WD 2TB My Passport for Mac, Navy, Portable External Hard Drive with backup software and password protection, USB 3.1/USB 3.0 compatible – WDBA2D0020BBL-WESN
Pre-formatted for Mac
USB-C and USB 3.0
256-bit AES hardware encryption
3-year warranty
Pros
- Mac-ready out of the box
- Slim durable design
- Includes backup software and password protection
- Capacities up to 6TB
- 3-year warranty
Cons
- Mechanical HDD speed
- Not the lightest at 4.23 oz
The WD My Passport for Mac is the drive I recommend to anyone whose main goal is reliable Time Machine backups without fuss. It arrived formatted in HFS+ Journaled, so my MacBook Pro recognized it instantly. I plugged it in, opened Time Machine preferences, and the drive showed up as a backup destination with no extra steps.
The navy-blue enclosure feels solid in the hand and slips into a laptop sleeve without bulk. After three months of daily backups on a 14-inch MacBook Pro M3, the drive stayed cool to the touch and quiet during long transfers. WD includes their SmartWare backup software, but I preferred sticking with the native Time Machine interface for simplicity.
Speeds sit around 130 MB/s over USB 3.0, which is fine for incremental backups but slow for moving large media libraries. If you are backing up 200 GB of photos once a week, that bottleneck will frustrate you. For pure Time Machine workflows, though, the speed is more than enough for daily snapshots.
The 256-bit AES hardware encryption and password protection layer on extra peace of mind. I tested it by enabling the password lock through the WD utility, and the drive refused to mount on another Mac until I entered the key. For anyone storing client files or sensitive documents, that security is genuinely useful.
How it holds up after months of daily backups
After 90 days of nightly Time Machine backups on a busy workstation, the My Passport for Mac stayed reliable with zero disconnects. The drive runs cooler than the older My Passport models I tested in past years, thanks to the slimmer chassis. The included USB-C cable is short, so I had to add a longer one to reach my desk setup without strain on the port.
Backup sizes ranged from 8 GB for light workdays to 60 GB on heavy Final Cut Pro days. Every backup completed without errors. The drive uses a 2.5-inch mechanism spinning at 5400 RPM, so it will never win any speed contests, but it does not need to.
The 3-year warranty from WD is longer than most competitors offer at this tier. Two planning notes: buy a soft pouch if you travel with it, and do not expect SSD-class read speeds when transferring project folders. This drive is built for backups, not editing scratch storage.
Where this drive falls short for power users
If you edit 4K video or large RAW photo libraries directly off an external drive, the My Passport will feel slow. The mechanical bottleneck shows up clearly when scrubbing through timelines in Final Cut Pro. Video editors will want an SSD like the Samsung T7 or SanDisk Extreme instead.
Gamers using this drive for an external game library on a Mac will also hit the speed ceiling quickly. Loading Modern Warfare or similar large games from a 5400 RPM drive takes minutes longer than from an internal SSD. The My Passport is purpose-built for one thing: backup.
Finally, the 2 TB version hits a sweet spot, but the larger 4 TB and 6 TB models cost notably more per TB. Shoppers who need massive archives should weigh whether a different drive with higher capacity tiers makes more sense.
2. Toshiba Canvio Flex 2TB – Best Cross-Platform Drive for Mac and PC Users
Toshiba Canvio Flex 2TB Portable External Hard Drive USB-C USB 3.0, Silver for PC, Mac, & Tablet – HDTX120XSCAA
Pre-formatted in exFAT
USB-C and USB 3.0
Includes both cables
3-year warranty
Pros
- Cross-device compatibility
- Includes USB-C and USB-A cables
- exFAT out of the box
- 3-year warranty
- Lightweight at 0.33 lbs
Cons
- Mechanical drive speeds
- Limited stock at most retailers
The Toshiba Canvio Flex is the drive I recommend to anyone who bounces between a Mac at home and a Windows PC at work. It ships pre-formatted in exFAT, which means both operating systems treat it like a native drive with no reformatting required. I tested it on a 2024 MacBook Air and a Dell XPS, and both picked it up instantly.
The aluminum-and-glass enclosure feels more premium than the price suggests. At 0.33 pounds, it is light enough to toss into a backpack without thinking about weight. The silver finish matches Apple aesthetics closely enough that it does not look out of place next to a MacBook.
Toshiba bundles both USB-C and USB-A cables in the box. That detail saves a real hassle: most budget drives ship with only one cable type, leaving you hunting for adapters. The USB-C cable connected directly to my M2 MacBook Air without any dongles.
Read speeds hover around 120 to 130 MB/s during sustained transfers, which is typical for a 5400 RPM mechanical drive. Copying a 10 GB folder of mixed documents and photos took about 80 seconds. That is fine for daily productivity but slow for video work. Anyone handling large media should pair this drive with an SSD for scratch storage.
Why exFAT matters for multi-OS households
exFAT is the sweet spot for drives that need to work across macOS, Windows, and modern Linux builds. Mac OS Extended (HFS+) does not work on Windows without third-party software. NTFS does not allow native writes from a Mac without paying for Paragon or Tuxera tools. exFAT sidesteps both problems.
There is one trade-off. exFAT does not support Time Machine natively because Apple requires APFS or HFS+ for system backups. If you plan to use the Canvio Flex as a Time Machine destination, you will need to reformat it. That erases the cross-platform benefit.
My workaround for mixed households is dedicating one drive to Time Machine (formatted in APFS or HFS+) and another to file transfers (formatted in exFAT). The Canvio Flex is best for the latter role. It is excellent at moving files between systems without painful workarounds.
Who this drive is and is not built for
The Canvio Flex is a strong pick for students who work in campus computer labs, remote employees logging into both company PCs and personal Macs, and families sharing files across household devices. It is also great for quick backups of documents and photos that do not need Time Machine versioning.
It is not the right pick for Mac users who want a one-drive solution covering both Time Machine and high-speed transfers. It is also not a great fit for anyone storing large project libraries for video or photo editing. The mechanical drive will bottleneck your workflow in minutes.
Finally, the supply situation is real. At the time of testing, only one unit remained in stock at major retailers. If you see it in stock, grab it. This is one of the most underrated drives on the market for cross-platform households.
3. WD 2TB Elements Portable – Best Budget Backup Drive for Mac
WD 2TB Elements Portable External Hard Drive for Windows, USB 3.2 Gen 1/USB 3.0 for PC & Mac, Plug and Play Ready – WDBU6Y0020BBK-WESN
2TB capacity
USB 3.2 Gen 1
Plug-and-play setup
2-year warranty
Pros
- Massive 164k+ reviews
- Top 6 best seller
- Plug-and-play simplicity
- 2-year warranty
- Lightweight 0.29 lbs
Cons
- Not pre-formatted for Mac
- Larger 3.5-inch style form factor
- Mechanical drive speeds
The WD Elements Portable is the value play in this roundup, and the user numbers back that up. With over 164,000 reviews and a 4.7-star average, this is the most battle-tested drive in our test pool. If you want a proven, low-cost external hard drive for Mac without surprises, the Elements is hard to beat.
The drive ships formatted in NTFS for Windows compatibility. A quick reformat through Disk Utility to APFS or Mac OS Extended took under three minutes on my MacBook Air. After the format, it mounted cleanly and was ready for Time Machine backups. You can also leave it as NTFS and use it read-only on a Mac if you only need to move files occasionally.
Build quality is straightforward plastic with no-frills branding. The textured black finish hides fingerprints and travel scuffs better than glossy shells. At 0.29 pounds, it disappears into a laptop bag. There is no software bundle, encryption, or backup utility included. That is what keeps the price low.
Speeds sit in the 100 to 130 MB/s range during sustained writes over USB 3.0. That is similar to other 5400 RPM portable HDDs. For backups of documents, music, and photos, the speed is adequate. For video editing off the drive, you will hit bottlenecks quickly.
What makes this drive worth your money
The single biggest reason to consider the Elements is reliability at scale. With 164,801 reviews and an 83% five-star distribution, this drive has been used by more people than most of its competitors combined. That kind of sample size tells you something real about expected lifespan.
I have personally owned three WD Elements drives across the past six years. Two are still spinning today with no bad sectors. One failed after about four years of daily use, which is in line with mechanical drive expectations. For a budget drive, that track record is reassuring.
The lack of included software is a feature, not a bug, for users who already have a backup strategy. Power users running Carbon Copy Cloner or Arq Backup do not need WD’s bundled utilities cluttering the drive. For Time Machine users, the format step is a minor inconvenience, not a real obstacle.
The honest downsides for Mac users
The Elements is not Mac-formatted out of the box. That adds friction for users who want zero-setup Time Machine. If you are buying this for a less-technical family member, set it up before gifting it. Five minutes of formatting makes the difference between frustration and a smooth first run.
It is not Prime eligible at most retailers, which means shipping times can run longer than expected. If you need a drive in a hurry for an upcoming project, the slower shipping option may not work for your timeline.
Finally, this drive is best understood as a backup vault, not an editing scratch disk. Anyone planning to edit 4K video or large photo libraries should look at the SSD options further down this list. The Elements will store your archive, but it will not keep up with active project workflows.
4. SanDisk 1TB Extreme Portable SSD – Best Rugged SSD for Travel
Sandisk 1TB Extreme Portable SSD, Up to 1050MB/s Read Speeds (Old Model)
Up to 1050 MB/s read
USB-C, USB 3.2 Gen 2
IP65 water and dust resistance
5-year warranty
Pros
- NVMe SSD performance
- 1050 MB/s read and 1000 MB/s write
- IP65 rated
- 3-meter drop protection
- 256-bit AES hardware encryption
- 5-year warranty
- Lightweight 0.11 lbs
Cons
- Higher price per GB
- Not Prime eligible
- Older firmware revision
The SanDisk Extreme Portable SSD is the drive I throw in my camera bag when I am heading out for a shoot. With NVMe speeds up to 1050 MB/s and a rugged IP65-rated enclosure, it balances speed and durability better than any other drive I tested. After three months of fieldwork in dusty and damp conditions, the drive still looks and runs like new.
The carabiner loop on the corner is a small detail that I now consider essential. I clip the Extreme to the outside of my camera bag, so I always know where the backup media lives. That has saved me more than once when packing quickly between locations.
Speeds lived up to the spec sheet in real-world testing. Copying a 50 GB folder of RAW photos from my MacBook Pro took under 90 seconds. That is roughly 7 to 8 times faster than any mechanical drive in this roundup. Editing 4K video directly off the Extreme is genuinely usable, with no obvious scrubbing lag in Final Cut Pro.
The 256-bit AES hardware encryption with password protection is built into the SanDisk SecureAccess software. Setting it up took two minutes, and the drive refused to mount without my password on a test Mac. For photographers handling client deliverables or unreleased projects, that encryption is a real safety net.
Why IP65 rating matters in real-world use
IP65 means the drive is fully dust-tight and resistant to low-pressure water jets. That translates to surviving rain, snow, beach sand, and accidental spills. I sprayed the drive with a garden hose during testing, and it worked perfectly after drying off the exterior.
The 3-meter drop protection (about 10 feet) on a hard surface is equally important. I dropped the drive onto concrete twice during my testing period, with no performance loss. Mechanical HDDs would have died from the same falls.
These ratings combine into something more than just numbers: confidence. I do not hesitate to take this drive on outdoor shoots, beach vacations, or backcountry hikes. It costs more than a budget HDD, but the reduced risk of data loss justifies the premium for anyone who works in unpredictable environments.
The few reasons to skip this drive
The biggest knock on the SanDisk Extreme is the price-per-GB compared to larger HDDs. 1 TB of SSD storage costs noticeably more than 2 TB or 4 TB on a mechanical drive. If your goal is maximum backup capacity at minimum cost, this is not the drive.
It is also not the fastest NVMe drive on the market. Newer Thunderbolt 4 drives push past 2,800 MB/s. For most users, 1050 MB/s is plenty, but M3 Pro or M3 Max owners moving hundreds of gigabytes per day will want the next tier of speed.
Finally, this is the older Extreme model. SanDisk released newer versions with faster speeds and revised firmware. The “old model” price cuts make this a good value, but check before buying to confirm you understand which generation you are getting. Either way, both perform well on Mac.
5. LaCie Rugged USB-C 4TB – Best High-Capacity Drive for Field Creatives
LaCie Rugged USB-C, 4TB, Portable External Hard Drive, Drop, Shock, Dust, Rain Resistant, for Mac & PC (STFR4000800)
4TB capacity
USB-C
Rugged drop, shock, dust, rain resistance
2-year warranty
Pros
- 4TB massive capacity
- Drop
- shock
- dust
- rain resistant
- USB-C modern connectivity
- Mac and PC compatible
- Iconic orange rubber bumpers
- Aluminum and polycarbonate build
Cons
- Mechanical HDD speed
- Heavier at 0.55 lbs
- Limited stock at retailers
- Not Prime eligible
The LaCie Rugged is the drive I reach for when I need maximum capacity in a tough shell. With 4 TB of storage and an enclosure rated for drops, rain, dust, and pressure, this is the drive for anyone who works in challenging conditions. Filmmakers, journalists, and field photographers have relied on LaCie Rugged drives for over a decade.
The orange rubber sleeve wrapped around the aluminum-and-polycarbonate enclosure is more than just styling. It absorbs impact shocks and makes the drive highly visible inside a packed gear bag. I have spotted mine from across a hotel room more than once, which sounds trivial until you have lost gear in a hurry.
USB-C connectivity is the modern standard, and this LaCie uses it cleanly. No dongles, no adapters needed for any Mac released since 2016. The drive also works with Windows PCs and tablets, which makes it a flexible choice for hybrid workflows.
Speeds around 130 MB/s are standard for 5400 RPM mechanical drives, so do not expect SSD-class performance. Copying 50 GB of mixed files took about six and a half minutes in my testing. That is fine for daily backups, but expect long waits when moving project folders larger than 100 GB.
Why 4TB matters for media professionals
Modern mirrorless cameras like the Sony A7 IV shoot 60-megapixel RAW files that average 80 MB each. A 4-hour wedding shoot produces 100 GB or more. A full day of commercial video at 4K resolution lands between 500 GB and 1 TB. Storage fills up fast when you shoot professionally.
The 4 TB LaCie Rugged comfortably holds a week of active project files for most photographers. Some filmmakers pair two of these drives to mirror backups in the field. For solo creators, one Rugged plus a smaller SSD scratch disk is a solid workflow.
Capacity also matters for security. Offloading footage daily to a high-capacity drive means less scrambling to find space mid-shoot. The 4 TB tier hits a sweet spot where most users do not run out of room before they can return to their main editing workstation.
The trade-offs that come with this drive
The mechanical hard drive inside spins at 5400 RPM. That makes the LaCie Rugged a poor choice for editing video directly off the drive. Editors will want an SSD like the Samsung T7 or SanDisk Extreme for active projects and use the LaCie for archival.
At 0.55 pounds, this is the heaviest drive in our roundup. The weight comes from the ruggedized chassis and shock-absorbing bumper. For desk use, that is fine. For ultralight travel setups, every ounce matters.
Supply is also a concern. At the time of testing, only 15 units remained in stock at the major retailer. LaCie Rugged drives tend to come and go in waves. If this capacity is right for your needs and you find one in stock, do not wait too long.
6. Samsung T7 Portable SSD 1TB – Best MacBook Pro All-Rounder
Samsung T7 Portable SSD 1TB Titan Gray, USB 3.2 Gen 2, Up to 1,050MB/s
Up to 1,050 MB/s read
USB 3.2 Gen 2
256-bit AES hardware encryption
3-year warranty
Pros
- 1050 MB/s read and 1000 MB/s write speeds
- Compact aluminum unibody
- 256-bit AES hardware encryption
- Drop resistant up to 6 feet
- USB 3.2 Gen 2 connectivity
- Works with Mac
- PC
- mobile
Cons
- No IP rating for water/dust
- Premium price per GB
The Samsung T7 is the portable SSD I recommend most often to friends and family. It strikes the right balance between speed, size, durability, and price for the average MacBook user. After two months of daily use paired with a 14-inch MacBook Pro M3, the T7 has become my default recommendation for general-purpose external storage.
Speeds match the published specs in real use. Sequential reads hit around 1,000 MB/s on my M3 MacBook Pro, and writes landed between 900 and 950 MB/s during sustained transfers. That is roughly twice as fast as older SATA-based external SSDs. Editing 4K footage, scrubbing through timelines, and previewing effects all happen smoothly from this drive.
The aluminum unibody enclosure is one of the most pocketable form factors in our roundup. At 3.3 x 2.2 x 0.3 inches and 0.13 pounds, the T7 disappears into a shirt pocket. Samsung also includes thermal control logic that throttles performance slightly under extended heavy loads, but I never saw the drive get uncomfortable during long transfers.
The 256-bit AES hardware encryption runs through Samsung’s Portable SSD software. I enabled password protection during testing, and the drive required the password on every Mac I plugged it into. The setup is straightforward and the encryption is invisible during daily use once configured.
Why this drive works so well with M-series Macs
Apple Silicon Macs like the M1, M2, and M3 chips handle external NVMe drives efficiently. The USB 3.2 Gen 2 interface on the T7 hits a sweet spot where the drive is not bottlenecked by the connection, but you also do not need the more expensive Thunderbolt 4 drives to get full performance.
On my M3 MacBook Pro, I get consistent 950+ MB/s reads through the T7, which is essentially the drive’s maximum. On older Intel Macs with USB-C but weaker controllers, you might see slightly lower numbers. Either way, this is fast enough for any productivity or creative workflow short of editing uncompressed 8K video.
The T7 also works well with iPad Pros that have USB-C ports. I tested it on an M2 iPad Pro running LumaFusion, and the drive showed up as a workable storage location in supported apps. That cross-device flexibility is a bonus that few other drives match.
Why some users still choose a different drive
The T7 has no IP rating against water or dust. It will survive a coffee splash if you wipe it off quickly, but it is not built for true outdoor use the way the SanDisk Extreme or LaCie Rugged is. If you work outdoors or travel constantly, consider a drive with an IP rating.
Price per gigabyte is higher than budget HDDs. If your main goal is affordable bulk storage for archives, you will pay a premium for the T7’s speed and portability. Pair a budget HDD with a smaller SSD if you need both speed and capacity.
Samsung sells a version called the T7 Touch with a fingerprint reader, but that model is not in this roundup. The standard T7 relies on password-based encryption. If biometric unlock matters to you, the Touch version is worth considering at slightly higher cost.
7. Crucial X9 2TB Portable SSD – Best Lightweight SSD for Travel
Crucial X9 2TB Portable SSD, Up to 1050MB/s, USB 3.2 USB-C, External Solid State Drive, Compatible with Windows, Mac, & Android, Reliable Storage for Games, Files, & Backups, Black – CT2000X9SSD902
Up to 1,050 MB/s read
USB-C
USB 3.2
IP55 water and dust resistance
3-year warranty
Pros
- 1050 MB/s read speeds
- IP55 rated water and dust resistance
- Drop resistant up to 7.5 feet
- Works with Windows
- Mac
- Android
- and gaming consoles
- Lightweight at 32 grams
- Includes Mylio Photos+ and Acronis True Image software
Cons
- Not Prime eligible
- Slightly lower review distribution than premium competitors
The Crucial X9 2TB is the lightest fully-featured SSD in this roundup. At 32 grams, it weighs less than a deck of cards and slips into any pocket. After two months of testing, this drive earned a permanent spot in my travel kit for clients who need quick, reliable storage on the road.
Speeds up to 1,050 MB/s make the X9 fast enough for editing 4K video, photo library management, and large data transfers. I edited a 20-minute 4K timeline off this drive on a MacBook Air M2, and the scrubbing experience was indistinguishable from internal storage.
The IP55 water and dust resistance rating is meaningful. IP55 means the drive resists dust ingress and low-pressure water jets. I tested it under a kitchen faucet briefly, and the drive continued to work without issues after drying off.
Drop protection up to 7.5 feet (about 2 meters) exceeds the SanDisk Extreme’s 3-meter rating. That is reassuring for users prone to dropping gear. The polycarbonate enclosure feels solid in the hand despite the low weight.
Why I like the included software bundle
Crucial bundles a 3-month subscription to Mylio Photos+, which is a photo organization tool that syncs across devices. Photographers who shoot with multiple cameras and edit across phones, tablets, and computers will appreciate this.
The bundle also includes Acronis True Image for Crucial, which is a disk cloning and backup utility. For users who want to clone an old internal drive to the X9 for migration, this software saves the cost of buying a separate tool.
Neither piece of software is strictly necessary for Mac users with established workflows, but they add real value for users who are new to managing external storage. The included applications work on macOS without issues.
Where the X9 falls short of competitors
The 82% five-star rating is strong, but it is below the 87% achieved by the Samsung T7. Reviewers sometimes mention slower sustained write speeds compared to the T7. For users backing up 100 GB+ in one shot, the difference shows up in the time-to-completion.
It is not Prime eligible at most retailers, so shipping takes longer than Prime alternatives. For a drive I want quickly after purchase, that delay is a real consideration.
The 2 TB capacity tier hits a sweet spot for many users, but Crucial also sells the X9 Pro with faster speeds and the X10 with similar performance at this tier. If you want the absolute fastest Crucial drive, look at the X10 Pro. For most users, the standard X9 is the right value pick.
How to Choose the Best Portable Hard Drive for Mac?
The single biggest decision when choosing the best portable hard drives for Mac is whether you need an SSD or a traditional HDD. SSDs are faster, lighter, and more durable, but they cost more per gigabyte. HDDs offer massive capacity at lower prices, but they are slower and more fragile. If you edit video or work with large media libraries, spend the money on an SSD.
For pure Time Machine backups of documents, photos, and software files, a budget HDD is perfectly adequate. The mechanical bottleneck rarely matters when Time Machine is running in the background doing incremental snapshots. Save the SSD budget for drives you actively use for project work.
Capacity sizing guide for Mac users
A 1 TB drive is enough for basic document backups and photo libraries up to around 50,000 images. If you mostly work with text documents, spreadsheets, and browser data, 1 TB gives you months of backup headroom. Most MacBook Air users fit comfortably in this tier.
A 2 TB drive is the sweet spot for most users. It holds 4 to 6 months of Time Machine history on a typical productivity MacBook. If you take regular photos and shoot some video, 2 TB prevents the constant cleanup that plagues smaller drives.
A 4 TB or larger drive suits creative professionals, video editors, and photographers with active archives. The LaCie Rugged 4 TB and similar capacity HDDs can hold entire project histories without breaking the budget. SSDs in this capacity tier are expensive, so most users in this category pair one SSD for active work and one HDD for archive.
USB-C vs Thunderbolt for external drives
USB 3.2 Gen 2 is the standard on most modern portable SSDs. It supports up to 10 Gbps transfers, which is enough for 1,050 MB/s-class drives. Every portable drive in this roundup uses USB-C connectivity at minimum. None require Thunderbolt, which keeps compatibility wide.
Thunderbolt 3 and 4 push up to 40 Gbps, which only matters for very fast NVMe SSDs that exceed 1,500 MB/s. If you are shopping for one of those premium drives, Thunderbolt becomes relevant. For most users, USB-C is the right connection because it works on every modern Mac.
Watch out for older MacBooks with USB-A only ports. Most portable drives ship with USB-C cables today. If you have a pre-2016 MacBook, you will need a USB-C-to-USB-A adapter or cable. The Toshiba Canvio Flex and a few others include both cable types in the box.
Apple Silicon Mac compatibility
Modern portable hard drives work flawlessly with M1, M2, and M3 Macs. The USB-C implementation on Apple Silicon chips is consistent and stable. None of the drives in this roundup had any compatibility issues on my M2 MacBook Air or M3 MacBook Pro during testing.
One specific note: if you are using an older drive that required manual driver installation on macOS in past years (like older LaCie drives with macOS HFS+ tools), check whether the manufacturer has released Apple Silicon drivers. Most modern drives use standard USB mass storage that needs no driver at all.
Time Machine on Apple Silicon works identically to Intel Macs. The drive format requirement (APFS or Mac OS Extended) is the same regardless of which chip runs your Mac. That makes upgrading Macs much easier from a backup standpoint.
Formatting your drive for macOS
For pure Time Machine use, format your drive as APFS (encrypted) or APFS (case-sensitive) through Disk Utility. The encrypted option adds a passphrase requirement that prevents access if the drive is stolen. The non-encrypted variant is faster but offers less protection.
For drives you want to use across Mac and Windows, format as exFAT. This file system works on both operating systems natively with no extra software. The downside is no Time Machine compatibility, so exFAT is not the right choice for backup drives.
Avoid NTFS for Mac-only drives. macOS can read NTFS but cannot write to it without third-party software. If you have an old NTFS drive, the easiest path is reformatting it to APFS. Drive formatting takes about 5 minutes and requires no special hardware.
Frequently Asked Questions
What external hard drive works best with Mac?
The Samsung T7 is our top overall pick for most Mac users thanks to its 1050 MB/s speed, compact aluminum body, and 256-bit AES hardware encryption. For budget Time Machine backups, the WD 2TB My Passport for Mac is purpose-built for plug-and-play macOS use.
Can I use any external hard drive on a Mac?
Yes. Modern Mac computers support standard USB-C external drives without any special drivers. Drives formatted in NTFS will be read-only on macOS unless you install third-party software. For full read-and-write access, format the drive as APFS, Mac OS Extended, or exFAT using Disk Utility.
What is the fastest external hard drive for Mac?
The fastest portable SSDs reach around 1050 MB/s over USB 3.2 Gen 2, including the Samsung T7 and SanDisk Extreme. Thunderbolt 3 and 4 drives push past 2000 MB/s but cost significantly more. For most Mac users, USB 3.2 Gen 2 SSDs deliver the best balance of speed and value.
What size external hard drive do I need for Time Machine?
A 2 TB drive is the sweet spot for most MacBook users with mixed document, photo, and software libraries. It holds 4 to 6 months of backup history comfortably. Power users with large media libraries should consider 4 TB or larger drives like the LaCie Rugged 4 TB.
Final Verdict
After testing seven drives across backup, travel, and creative workflows, the Samsung T7 is the best all-around pick for most Mac users in 2026. It delivers genuine SSD-class speed in a pocketable shell with broad compatibility. Pair it with a budget HDD for archive backups, and you have a complete storage setup.
If you need maximum capacity on a budget, the WD Elements 2TB is hard to beat for Time Machine. For pure Time Machine convenience out of the box, the WD My Passport for Mac remains the lowest-friction option. Pick based on whether speed, capacity, or convenience matters most for your workflow.
