Silicon Power Ace A55 Review

The Silicon Power Ace A55 targets buyers upgrading genuinely older systems, offering SATA speeds at the low end of the price spectrum for basic boot-drive and everyday-file storage needs rather than performance-sensitive workloads.

At up to 560 MB/s read and 530 MB/s write, this drive's rated numbers reach the top of the SATA interface's ceiling despite its bargain pricing, a genuinely strong value proposition for cost-conscious upgraders. Against the ADATA Ultimate SU800, covered elsewhere on this site, both target similar value-conscious SATA buyers at comparable pricing. Against the Patriot Burst Elite, also covered elsewhere on this site, that drive uses QLC NAND for an even lower price at reduced sustained performance.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Best for

Buyers upgrading an older system on the tightest possible budget who still want solid SATA speed. This drive delivers surprisingly strong rated numbers for its bargain price.

Not for

Not for buyers running write-heavy workloads that would benefit from DRAM caching consistency. The Kingston KC600, covered elsewhere on this site, better serves that need.
