Unverified50% confidenceFactExact time
SSDs use flash memory chips with random access latency typically below 0.1 milliseconds, and almost no difference between random and sequential access speeds, so traditional defragmentation offers almost no performance benefit for SSDs.

UnverifiedIn the SSD era, the random reads of flash memory have almost no seek latency, rendering defragmentation meaningless and potentially even shortening drive lifespan due to additional write operations.80% similarUnverifiedThe access latency of object storage is typically in the range of tens to hundreds of milliseconds, far higher than local SSD (microsecond-level) or memory (nanosecond-level).73% similar
