My oldest SATA SSD (which is also my boot drive) is not showing the same
kind of performance it did when it was new. I only discovered it
recently after buying a new secondary SATA SSD, which I benchmarked, and
then as a comparison I compared it against the older one. The new one is showing a peak sequential read of 456 MB/s and a write of 450 MB/s. But
the older one is only showing 210 MB/s & 160 MB/s respectively; it used
to show performance more comparable to the newer drive when it was new.
It sounds like this drive has downgraded itself from SATA-3 down to
SATA-2. Is there a way to see if a drive is running in either SATA-2 or
-3 mode? All of my SATA ports are supposed to be SATA-3 capable.
