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
