Our Pick

SanDisk

SanDisk Extreme Portable 2TB
8.6/10

A 2TB IP55 rugged portable — the budget sibling of the Extreme Pro 2TB. Same IP55 body and 1050 MB/s read, just dropped to a 3-year warranty and slower sustained writes on long transfers. Worth it if your use case is backup and console library overflow rather than video editing.

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.
