SSD-iq: Uncovering the Hidden Side of SSD Performance

Summary: Commercial data-center SSDs with similar headline specs show large, undocumented performance divergence that materially affects DB performance, particularly for writes. SSD-iq: a benchmark adding four metrics to expose controller and write-path behaviors missed by capacity/sequential/random specs. (summarized by gpt-5-mini on Feb 09 2026)
