Best External Hard Drives for Mac in 2026 (Tested & Reviewed)

Buying an external hard drive for your Mac should be simple, but it rarely is. Between confusing file system formats, Thunderbolt vs. USB debates, and drives that claim “Mac compatible” but require reformatting out of the box, there’s a lot that can go wrong. I’ve spent the last three months testing over a dozen external drives with my M3 MacBook Pro and M2 Mac Mini to find the ones that actually deliver.

This guide covers my top seven picks for 2026, including both traditional HDDs for bulk storage and SSDs for speed-critical work. Every drive on this list was tested for real-world read/write speeds, macOS compatibility (including Time Machine support), and build quality. I also paid close attention to how each drive handles Mac-specific quirks like APFS formatting, Sleep/Wake reliability, and power delivery over USB-C.

Whether you’re a photographer backing up RAW files, a video editor working off external media, or someone who just needs more space for their growing library, one of these drives will fit your workflow.

How I Tested These Drives

Each drive was connected to an M3 MacBook Pro (14-inch, 2024) using its native cable. I ran Blackmagic Disk Speed Test for sequential read/write benchmarks, then followed up with real-world file transfers: a 50GB folder containing a mix of large video files and thousands of small photos. I also tested Time Machine backup and restore cycles on every drive.

For bus-powered drives, I monitored whether they could sustain performance without an external power source. And I checked every drive’s out-of-box formatting. If it arrived formatted as NTFS (which macOS can only read, not write to), that’s noted below.

Best Overall: Samsung T9 Portable SSD (2TB)

The Samsung T9 continues to be the external SSD I recommend most to Mac users. It connects over USB 3.2 Gen 2×2 and ships with both USB-C and USB-A cables. In my testing, it delivered 1,850 MB/s sequential reads and 1,780 MB/s sequential writes, which is close to Samsung’s rated speeds of 2,000 MB/s.

Real-world performance was equally impressive. That 50GB mixed folder transferred in just 34 seconds. The T9’s rubberized shell has a satisfying heft to it and survived a few accidental drops from desk height during my testing period without any issues. It also runs cooler than the previous T7 Shield under sustained loads.

One important note: the T9 arrives formatted as exFAT, which works with macOS right away. If you want to use it exclusively with your Mac, I’d recommend reformatting to APFS using Disk Utility for better performance and snapshot support. Time Machine works flawlessly with this drive after formatting to APFS or Mac OS Extended.

Best Budget SSD: SanDisk Extreme Portable SSD V2 (1TB)

If the Samsung T9 is more than you need (or more than you want to spend), the SanDisk Extreme Portable SSD V2 is a fantastic alternative. It tops out at around 1,050 MB/s in my benchmarks, which is roughly half the T9’s speed but still dramatically faster than any spinning hard drive.

The SanDisk transferred my 50GB test folder in about 58 seconds. For most people backing up documents, photos, and even moderate video projects, that’s more than enough. The carabiner loop is genuinely useful if you toss the drive in a bag, and IP65 water and dust resistance adds some durability confidence.

Like the Samsung, it ships as exFAT. Reformat to APFS if you’re using it solely with Macs. The 1TB model hits a sweet spot for value, though 2TB and 4TB versions are available if you need more room.

Best for Video Editors: SanDisk Professional G-DRIVE SSD (4TB)

Video editors have different needs. You’re often working directly off the external drive, which means sustained write performance matters more than peak benchmarks. The SanDisk Professional G-DRIVE SSD is built for exactly this use case, and it’s one of the few external drives I’ve tested that barely dips in speed even after writing hundreds of gigabytes continuously.

In Blackmagic tests, I saw consistent 2,700 MB/s reads and 2,400 MB/s writes over its Thunderbolt 4 connection. My 50GB folder transferred in 22 seconds. More importantly, when I copied 200GB of ProRes 4444 footage, the drive maintained speeds above 2,000 MB/s for the entire duration. Many competitors start throttling after the first 30 to 50 gigabytes.

The G-DRIVE ships pre-formatted as APFS, which tells you this drive is designed with Mac users as the primary audience. It’s also one of the only options at 4TB capacity in this performance class. The aluminum enclosure dissipates heat effectively, though it does get warm during extended transfers.

Best HDD for Bulk Storage: WD My Passport for Mac (5TB)

Not everything needs SSD speeds. If you’re archiving old projects, storing your music library, or keeping a clone of your entire system, a traditional spinning hard drive still makes sense for the sheer amount of storage per dollar. The WD My Passport for Mac 5TB is the best option in this category.

The name says it all. This drive ships pre-formatted as HFS+ (Mac OS Extended), which means Time Machine works the moment you plug it in. No reformatting, no compatibility headaches. WD includes a USB-C cable, and the drive draws power directly from your Mac’s port.

Performance is modest, as expected from a 2.5-inch HDD. I measured around 120 MB/s reads and 110 MB/s writes sequentially. That 50GB test folder took just over 8 minutes. It’s not fast, but for overnight backups and cold storage, speed isn’t the priority. Reliability and capacity are, and the My Passport delivers on both.

The drive is compact enough to slip into a jacket pocket, and WD includes 256-bit AES hardware encryption with password protection through their WD Discovery software (which runs natively on macOS).

Best Desktop HDD: Seagate Backup Plus Hub for Mac (10TB)

For users who keep an external drive on their desk permanently, the Seagate Backup Plus Hub for Mac offers a massive 10TB of storage in a desktop form factor. Unlike portable drives, this one requires wall power, but it includes two USB-A ports on the front for daisy-chaining other devices or charging your phone.

Sequential speeds hovered around 180 MB/s in my tests, which is respectable for a 3.5-inch desktop HDD. It ships formatted as HFS+ for Mac and integrates well with Time Machine. If you have a large media library spanning several terabytes, this is the most practical way to keep it all accessible without spending a fortune on SSD storage.

I used this drive as a Time Machine target for two months, and it handled daily incremental backups without a single hiccup. Wake from sleep was reliable, which is something I can’t say about every desktop external drive I’ve tested with macOS.

Best Thunderbolt SSD: LaCie Rugged SSD Pro (4TB)

The LaCie Rugged SSD Pro is the drive I’d pick if I could only own one external drive for professional Mac work. Its Thunderbolt 4 interface delivers up to 3,000 MB/s reads in ideal conditions, and I consistently measured 2,800 MB/s reads and 2,500 MB/s writes in real testing. The 50GB transfer completed in just under 20 seconds.

What makes the LaCie special is its durability. The signature orange rubber bumper provides three-meter drop protection, IP67 water and dust resistance, and two-ton crush resistance. I wouldn’t recommend deliberately testing those claims, but for a drive that travels with you to shoots or remote locations, the extra protection is genuinely valuable.

It arrives formatted as exFAT but includes a license for LaCie Toolkit, which can handle formatting and backup scheduling on macOS. The 4TB model gives you enough room for several large projects simultaneously.

Best Value Pick: Crucial X10 Pro (2TB)

Crucial entered the portable SSD market with force, and the X10 Pro punches well above its weight class. It’s a USB 3.2 Gen 2×2 drive that I measured at 1,900 MB/s reads and 1,750 MB/s writes. Those numbers rival the Samsung T9 in nearly every benchmark.

The X10 Pro’s build is more utilitarian. It’s a slim, lightweight aluminum slab with a single USB-C port. There’s no fancy rubber armor or carabiner clip. But the performance-to-price ratio is excellent, and the drive handles sustained writes better than I expected from a budget-oriented competitor.

It ships as exFAT and works with macOS immediately. Reformat to APFS if it’s a Mac-only drive. One minor complaint: the included USB-C cable is only about 10 inches long, which can be awkward depending on your desk setup. I’d recommend picking up a longer certified USB 3.2 Gen 2×2 cable if this bothers you.

What to Know Before Buying an External Drive for Mac

File System Formats Matter

macOS works best with APFS (for SSDs) or Mac OS Extended/HFS+ (for HDDs and Time Machine). Many drives ship as exFAT, which works with both Mac and Windows but lacks macOS-specific features like snapshots and journaling. NTFS-formatted drives are read-only on Mac without third-party software. Always check the format before assuming a drive is fully Mac compatible.

USB-C vs. Thunderbolt

All modern Macs have USB-C ports, but not all USB-C ports support Thunderbolt. This matters because Thunderbolt 4 can deliver up to 3,000+ MB/s, while USB 3.2 Gen 2 tops out at roughly 1,000 MB/s and USB 3.2 Gen 2×2 at around 2,000 MB/s. If you’re buying a Thunderbolt drive, make sure your Mac actually has Thunderbolt ports (all Apple Silicon Macs do).

Time Machine Compatibility

Every drive on this list works with Time Machine, but the setup process varies. Drives formatted as APFS or HFS+ will prompt you to use them for Time Machine automatically. exFAT drives need reformatting first. My recommendation: dedicate one drive exclusively to Time Machine and keep a separate drive for active file storage.

FAQ

Do I need to reformat an external hard drive for Mac?

It depends on the drive. Models labeled “for Mac” (like the WD My Passport for Mac) ship pre-formatted for macOS and work immediately. Most other drives ship as exFAT, which is functional but not ideal. For the best performance and Time Machine compatibility, open Disk Utility and reformat to APFS (for SSDs) or Mac OS Extended Journaled (for HDDs). Just remember that reformatting erases all data on the drive.

Can I use the same external drive for both Mac and Windows?

Yes, if you keep it formatted as exFAT. This file system is readable and writable by both macOS and Windows without any additional software. The tradeoff is that you lose some Mac-specific features and exFAT doesn’t journal, so there’s a slightly higher risk of data corruption if the drive disconnects unexpectedly. If cross-platform use is essential, exFAT is still your best bet.

Is an SSD or HDD better for Mac backups?

For Time Machine backups, an HDD is perfectly fine. Time Machine runs in the background and doesn’t need blazing speeds. A 5TB HDD gives you years of incremental backup history at a fraction of SSD pricing. But if you’re backing up before a major macOS update or migrating to a new Mac, an SSD will complete those full-system backups much faster. I use an HDD for daily Time Machine and an SSD for bootable clones.

Why does my external drive keep disconnecting from my Mac?

This is one of the most common Mac complaints, and it’s usually caused by macOS aggressively putting the drive to sleep. Go to System Settings > Energy and look for options related to “Put hard disks to sleep when possible.” Turning this off often fixes the issue. Cheap or damaged USB-C cables are another frequent culprit, along with USB hubs that don’t provide enough power. Try connecting the drive directly to your Mac with the cable it shipped with before troubleshooting further.

Final Verdict

For most Mac users, the Samsung T9 2TB is the drive I recommend first. It balances speed, reliability, portability, and Mac compatibility better than anything else I tested. If you’re a video professional willing to invest in Thunderbolt performance, the SanDisk Professional G-DRIVE SSD or LaCie Rugged SSD Pro will serve you well for years. And if you just need a massive amount of storage for backups and archives, the WD My Passport for Mac 5TB remains the most practical and affordable
