Best Portable SSD for Mac
Every modern Mac has USB-C or Thunderbolt ports, making external SSDs the fastest way to expand storage. This page ranks portable SSDs by price per terabyte so you can find reliable, Mac-compatible external storage without overpaying for a brand name.
USB-C vs Thunderbolt on Mac
USB 3.2 Gen 2 (10 Gbps) portable SSDs deliver around 1,000 MB/s, fast enough for video editing proxies, photo libraries, and Time Machine backups. Thunderbolt 3/4 drives push 2,800 MB/s but cost significantly more. For most Mac users, USB-C at 10 Gbps is the practical sweet spot.
Quick Verdict
- Who this is for
- MacBook, iMac, Mac Mini, and Mac Studio owners who need portable external storage for backups, file transfers, or expanding limited internal storage.
- What usually wins
- A 1–2 TB USB-C portable SSD from Samsung, SanDisk, or Crucial. Thunderbolt drives only if you regularly transfer very large video files and need sustained 2,000+ MB/s speeds.
- Prioritise
- Price per TB with a USB-C 10 Gbps interface. Ensure macOS compatibility (APFS or exFAT formatting). Rugged build quality if you travel with the drive.

How to Choose
Choosing a portable SSD for Mac comes down to a few key factors.
Interface speed
USB 3.2 Gen 2 (10 Gbps) delivers ~1,000 MB/s and is sufficient for most workflows. USB 3.2 Gen 2x2 (20 Gbps) and Thunderbolt (40 Gbps) are faster but the drives cost more. Match the interface to your actual transfer needs.
File system
Most portable SSDs ship formatted as exFAT (cross-platform). For Time Machine, you will need to reformat to APFS or Mac OS Extended (HFS+). If you share the drive between Mac and Windows, keep exFAT.
Durability
Portable drives get tossed in bags and dropped. Look for IP55+ water/dust resistance and drop ratings if you travel. Samsung T7 Shield, SanDisk Extreme, and LaCie Rugged are popular rugged options.
Bus power
All portable SSDs run on bus power from the USB-C or Thunderbolt port. No external power adapter needed. This is a key advantage over portable HDDs, which sometimes struggle with power-hungry 2.5-inch drives on low-power ports.
Frequently Asked Questions
What is the best portable SSD for a Mac?
Any USB-C portable SSD running at USB 3.2 Gen 2 (10 Gbps) speeds — around 1,000 MB/s in practice — is fast enough for photo editing, video proxy workflows, and Time Machine backups on a Mac. Samsung T7, SanDisk Extreme, and Crucial X9 are popular options that reliably support APFS formatting. The tables on this page rank external SSDs by price per TB so you can find the best value on the day you buy.
Is Thunderbolt worth paying extra for a Mac external SSD?
Only if you regularly transfer very large files. USB 3.2 Gen 2 at 10 Gbps delivers ~1,000 MB/s — fast enough to edit 4K ProRes proxies or transfer a full photo shoot in minutes. Thunderbolt 3/4 drives push 2,800 MB/s, but few workflows saturate that. If you work with uncompressed 4K RAW or large DaVinci Resolve timelines daily, Thunderbolt earns its premium. For most Mac users, USB-C Gen 2 is the practical sweet spot.
Do I need to reformat a portable SSD for Mac?
Usually yes. Most portable SSDs ship as exFAT (cross-platform). For Time Machine, macOS requires APFS (macOS 11+) or Mac OS Extended (HFS+). Open Disk Utility, select the drive, click Erase, and choose APFS — it takes seconds. Keep exFAT if you also need the drive to work on Windows machines.
Can I use a portable SSD as a Time Machine backup on a MacBook?
Yes. A portable SSD makes an excellent Time Machine backup drive for a MacBook — silent, compact, and much faster than an external HDD for the initial backup. Reformat the drive to APFS first. Apple recommends the backup drive be 2–3× your Mac's internal storage. A 1 TB SSD is enough for a MacBook with a 256–512 GB internal drive; 2 TB gives more backup history.
What size portable SSD should I buy for a Mac?
1 TB suits most Mac users for file transfers and portable work. 2 TB is the better choice if you want to carry a full photo library, video project files, or a complete Time Machine backup alongside other files. Check the live price-per-TB rankings on this page — at 2 TB the per-TB cost is often similar to or lower than 1 TB, making it the better buy if budget allows.
