ADATA Ultimate SU800 Review

The ADATA Ultimate SU800 has remained a fixture of the value SATA category for years, consistently delivering top-tier SATA speed figures at pricing that undercuts several bigger-name competitors offering comparable specifications.

At up to 560 MB/s read and 520 MB/s write, this drive matches the top-tier SATA numbers from more established brands, backed by a long production track record that gives buyers confidence in its reliability. Against the Crucial MX500, covered elsewhere on this site, both deliver comparable top-tier SATA performance, with this ADATA drive generally available at a somewhat lower price. Against the Silicon Power Ace A55, also covered elsewhere on this site, that drive trades this SU800's DRAM-backed performance for a lower price at reduced consistency.
