WD Elements SE 2TB
Score: 47/100Rankings

The WD Elements SE 2TB Portable SSD offers a budget-friendly, ultra-compact solution with reliable 400 MB/s performance, making it suitable for casual backups and travel, though its legacy Micro-USB interface and lack of encryption limit its appeal for power users.

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.

Products in the top-left offer the best value (high score, low price).

Professional reviewers consider the X6 a serviceable, budget-friendly portable SSD that works well for everyday tasks but is hampered by its SATA-based internals and DRAM-less design, recommending PCIe-based alternatives for power users.
Consumers appreciate the X6's reliability, pocket-size convenience, and price, though many note that real-world speeds fall short of the advertised 800 MB/s and that performance drops after the cache is exhausted.

Brad Moon of Forbes praised the Elements SE as a cheap, affordable SSD ideal for casual use and backups, highlighting its sub-$120 price, pocket-size, and durability while noting the outdated Micro-USB port and modest speed compared to premium drives.
Everyday users rate the drive highly for reliability, ease of use, and ultra-compact durability, but commonly complain about the legacy Micro-USB connector and slower-than-expected transfer speeds.
