Corsair EX100U 2TB vs SanDisk Extreme Portable 1TB

Compare Corsair EX100U 2TB and SanDisk Extreme Portable 1TB side by side. Both are 2TB USB 3.2 Gen 2x2 external SSDs, but they differ in speed, design, and value. Here's how they stack up.

Corsair

Corsair EX100U 2TB
8.5/10

A 2TB Gen 2x2 portable SSD in the same aluminum-and-rubber body as the 1TB. Write speed drops slightly to 1800 MB/s on the 2TB variant — a real-world trade-off for the larger NAND die. Still above 2GB/s on long transfers as long as the host is Gen 2x2.

SanDisk

SanDisk Extreme Portable 1TB
8.5/10

The non-Pro Extreme is the lower-cost sibling — same 1050 MB/s rated read and IP55 rugged body, but writes top out well below Extreme Pro on sustained workloads. A solid buy when the write-speed gap doesn't matter (game consoles, file transfer, backup) but the rugged rating does.
