ADATA XPG SX850 128 GB

This is a 128GB 2.5" SSD on the SATA interface. Sequential throughput reaches 550 MB/s reads and 520 MB/s writes. SATA throughput caps near 550 MB/s — fine for game libraries and backups, slower for heavy scratch work. PlanMyPC's builder flags compatibility problems automatically and tracks the latest drive deals from multiple stores.

Warranty coverage follows ADATA's standard policy — confirm regional terms on the listing. The full specification sheet below breaks out every listed detail, and the compatibility checker flags conflicts with parts already in your build. If this drive is not quite the right fit, the category page lists close alternatives at similar prices for a quick side-by-side comparison.
