WD Elements SE 1TB
Score: 55/100Rankings

The Crucial X6 1TB offers an ultra-light, budget-friendly portable SSD with decent everyday performance, but its QLC, DRAM-less design means speeds fall short of the 800 MB/s claim and it lacks hardware encryption.

The WD Elements SE 1TB Portable SSD offers budget-friendly storage with decent 400 MB/s speeds in a tiny, lightweight case, but its outdated Micro-USB interface and lack of encryption limit its appeal for power users.
