Crucial X6 1TB vs Sabrent Rocket Nano V2 4TB

Crucial

Crucial X6 1TB
7.8/10

The X6 is Crucial's budget Gen 2 line — half the speed of the X9 Pro at typically half the price. A sensible choice for game-library expansion on PS5/Xbox or as a Time Machine drive, where sustained write speed matters far less than capacity-per-dollar.
