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.

Transcend

Transcend ESD310C Portable 1TB

7.6/10

A tiny 1050-class Gen 2 portable from a long-established memory brand. The ESD310C is among the smallest 1TB Gen 2 SSDs in retail -- small enough to be lost in a bag. Buy it for the form factor over sustained performance.
