ADATA

ADATA SE800 2TB
7.6/10

The 2TB SE800 keeps the same tiny plastic body of the 1TB and bumps the SLC cache budget. The budget-friendly per-TB makes it a viable choice for game-library cold storage where sustained write speed takes a back seat to capacity-per-dollar.

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.
