Why is the SSD performance much slower than benchmarks for the same device


Vertex 3 drives tend to benchmark much higher and my number are almost indicative of a SATA2 setup but as you can see from the info, I am in SATA 3.

Any ideas of what could be misconfigured?

Check that:

  1. Drive firmware is the very latest.
  2. That the SATA cable itself isn't old/damaged
  3. Alternate bench marking software AS SSD is popular too.
  4. That the SSD diagnostic information reports 'healthy' try the SSDLife app.

Also interference may be an issue, processes running in background, i.e.

  1. Indexing service keeping the drive/OS busy
  2. Backup software
