WD Black P50 Game Drive SSD Portable 2TB
8.6/10

The 2TB Black P50 doubles the SLC cache budget of the 1TB — sustained writes hold 2000 MB/s noticeably longer than on the 1TB. RGB-free Gen 2x2 with a 5-year warranty is genuinely rare; the chief competitor is the Kingston XS2000 2TB, also 5-year but lower price.
