Score: 90/100Rankings
A rugged, stick-form factor 2 TB SSD designed for PS5/PS4 gamers. It delivers up to 600 MB/s via USB 3.2 Gen 2, offers AES-256 encryption and IP55 protection, but is limited to a USB-A interface and can warm under heavy use.
The Crucial X6 1TB is an affordable, ultra-light portable SSD with decent everyday performance, but its QLC NAND and DRAM-less architecture prevent it from delivering the high sustained speeds some users expect.
