[[File:480 GB OCZ-AGIL ITY3.png|upright=1.6|thumb|Benchmark of a 500GB SATA-2 SSD ([[OCZ]] Agility-3, circa 2011), showing about 230 MB/s reading speed (blue), 210 MB/s writing speed (red) and about 0.1 ms seek time (green), all independent from the accessed disk location. As of 2026, Gen5 SSDs can reach up to 15GB/s, a 60x improvement over this SSD.]]


Traditional HDD [[Benchmark (computing)|benchmarks]] tend to focus on the performance characteristics such as [[rotational latency]] and [[seek time]]. As SSDs do not need to spin or seek to locate data, they are vastly superior to HDDs in such tests. However, SSDs have challenges with mixed reads and writes, and their performance may degrade over time. Therefore, SSD testing typically looks at when the full drive is first used, as the new and empty drive may have much better write performance than it would show after only weeks of use.{{cite web |title=Benchmarking Enterprise SSDs |url=http://www.stec-inc.com/downloads/whitepapers/Benchmarking_Enterprise_SSDs.pdf |url-status=dead |archive-url=https://web.archive.org/web/20120507070249/http://www.stec-inc.com/downloads/whitepapers/Benchmarking_Enterprise_SSDs.pdf |archive-date=2012-05-07 |access-date=2012-05-06}}
