ADATA

ADATA SE800 Portable 2TB
7.6/10

The 2TB SE800 keeps the same tiny plastic body of the 1TB version -- awwardly small for 2TB. Budget pricing per-TB makes it a value buy for PS5/Xbox cold library expansion, where sustained write speed takes a back seat to capacity-per-dollar.

Seagate

Seagate One Touch SSD Portable 2TB
7.8/10

The 2TB One Touch is the realistic minimum for game-library cold storage and Time Machine backups at typical Seagate sale pricing. The larger die stack holds the rated 1030 MB/s write distinctly longer than the 1TB variant before SLC cache exhausts.
