Best SSD for Mac 2026: External Drives, Thunderbolt Options & Apple Silicon Optimization
Quick Answer+
The Samsung T7 Shield 2TB is the best external SSD for most Mac users — fast USB 3.2 speeds (1,050 MB/s), rugged IP65 design, and reliable Mac compatibility. For maximum speed, the SanDisk Pro-Blade Transport with Thunderbolt 4 delivers 3,000 MB/s — ideal for video editors on MacBook Pro. Budget pick: Crucial X9 Pro matches T7 Shield performance at a lower price. Note: Modern Macs have soldered internal storage that cannot be upgraded — external drives are your only expansion option.
Mac users face a unique storage challenge: Apple has made internal storage non-upgradeable on virtually all modern Macs. Whether you have a MacBook Air, MacBook Pro, iMac, or Mac Studio, adding storage means going external.
The good news: today’s external SSDs are fast, reliable, and some Thunderbolt options nearly match internal drive performance. This guide covers the best options for every Mac workflow.

Understanding Mac Storage Options
Why External? The Apple Storage Reality
Apple’s design philosophy prioritizes thin, sealed devices. The consequence:
- All Apple Silicon Macs: Storage is soldered to the motherboard — completely non-upgradeable
- Intel Macs (2016+): Storage is proprietary and extremely difficult to replace
- Older Intel Macs (pre-2016): Some models had replaceable SSDs, but finding compatible drives is challenging
The bottom line: For any Mac purchased in the last 5+ years, external storage is your only practical expansion option.
Connection Types
| Connection | Max Speed | Mac Compatibility | Cable Length |
|---|---|---|---|
| Thunderbolt 4 | 3,000+ MB/s | All Apple Silicon + TB-equipped Intel | Up to 2m (active) |
| Thunderbolt 3 | 2,800 MB/s | All TB3-equipped Macs | Up to 2m (active) |
| USB 3.2 Gen 2×2 | 2,000 MB/s | Limited Mac support | Up to 1m |
| USB 3.2 Gen 2 | 1,050 MB/s | All USB-C Macs | Up to 2m |
| USB 3.2 Gen 1 | 450 MB/s | All USB Macs | Up to 2m |
Thunderbolt drives cost 2-3x more than USB drives. The speed difference matters for video editing and large file transfers but is imperceptible for general use, Time Machine backups, and document storage. Most users should save money with USB 3.2.
Apple Silicon Considerations
M1/M2/M3/M4 Macs have some specific storage behaviors:
- Unified Memory: macOS uses SSD for virtual memory more aggressively
- APFS: Optimized for Apple’s file system (all recommended drives work)
- Secure Erase: macOS handles SSD TRIM automatically for connected drives
- Sleep/Wake: Some drives handle Mac sleep better than others (Samsung and SanDisk excel)
