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.
