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.

WD My Passport SSD Portable 4TB
