For General Users

Linux Users

Although all models of SSD should work with Linux some do not have Linux software tools available to optimise the drive. See: SSD_Linux

Getting Technical

Disk Controller

Most SSD have SATA III (6 Gb/s) Interface. This equates to approx 750 MB/s, that is 50% more than contemporary SSD can deliver.

Older mainboards having only SATA II controllers generally work, but will deliver a little less than the advertised speed

SSD are manufuctured in three different form factors:

  • 2.5" SATA
  • mSATA
  • M 2 (previously NGFF)

All have different connectors and are not directly interchangeable

  • adapters to convert mSATA or M 2 to SATA interface are available

Support for TRIM

SSD require periodic use of the TRIM command

  • if an SSD reports "disk full" and deleting files fails to create usable space then that is an indication that TRIM is either not implemented or not supported
