Samsung T7 2TB Gray
Score: 99/100
SanDisk Extreme PRO 4TB USB4
Score: 92/100Rankings

The Samsung T7 2TB offers the same high-speed performance as the 1TB model in a slightly larger capacity, with a lightweight metal case, strong encryption and dual cables. It shares the same drawbacks of missing biometric security and limited warranty.

The 4 TB SanDisk Extreme PRO Portable SSD uses USB4 to deliver near-internal SSD performance with up to 3800 MB/s reads, while offering rugged IP65 protection and hardware encryption. It shines on Thunderbolt-4 hosts but can fall back to slower speeds on older machines, and its larger size makes it less pocket-friendly.

Reviewers give the T7 2TB 4.0-4.5 stars, applauding its blazing speeds and encryption while noting the lack of fingerprint authentication and a shorter warranty compared with premium drives.
Users praise the instant-like transfers and pocket-sized form factor, but complain about Linux encryption incompatibility and the need to reformat for macOS.

“Near-rated high sequential read/write speeds (~1,050/1,000 MB/s)”

“Ultra-compact credit-card size and lightweight (~2 oz)”

“Durable aluminum unibody with 6.5 ft drop resistance”




Professional reviewers commend the Extreme PRO USB4 SSD for its blazing peak speeds and rugged build, but repeatedly warn that real-world performance hinges on a fully compatible 40 Gbps host. PCWorld and The SSD Review note that without BIOS or firmware updates the drive often falls back to slower USB 3.x rates, and some USB4 implementations cap at 32 Gbps, keeping it slightly behind rivals like the Samsung X5. Nonetheless, on Thunderbolt-4 Macs the drive consistently hits its advertised 3800 MB/s reads.
Everyday users, especially video editors and photographers, praise the drive's speed, plug-and-play ease, and durable design for on-location work. The average rating hovers around 4.5 / 5, though recurring complaints focus on initial connection hiccups, the larger form factor, and occasional speed throttling after the cache is exhausted.
