Defrag on SSDs in Windows 10 runs Trim. And it does do that automatically on a schedule if you don't change anything. Actual defragmentation on an SSD is way less useful because SSDs don't have killer seek latencies like spinning rust plates did, and it would be small-scale harmful because of write wear. And your SSD's onboard controller would likely thwart your efforts anyway, because of wear leveling.
- Retric 7y agoThat’s 1/2 right SSD’s do have fragmentation issues, but it’s about IOPS not latency. http://www.dbta.com/Editorial/Trends-and-Applications/Does-Fragmentation-Hurt-SSD-Performance-105652.aspx http://www.dbta.com/Editorial/Trends-and-Applications/Does-F... TRIM is also important, but it’s a different issue.
- Klinky 7y agoThat article makes claims of 25% reduction in perf with no data to back it up, then mentions fragmention leads to system instability, requiring reboots... What? Again no data given to back up these claims. It's also SAN/Enterprise-centric. Even if you lost 25% perf, you're going from 200,000 IOPs/sec to 150,000 IOPs/sec. This is still plenty fast.
