Change disk ssd. How check which SATA version is supported?

Solution 1:

First know that all SATA versions are backward compatible. This means that if you insert a SSD that is SATA 3.0 to a computer that only supports up to SATA 2.0, the SSD will still work but at the speed of a SATA 2.0.

IF you look at the specs for that computer you will see that it has support for SATA 2.0 and SATA 3.0:

Up to 1TB [SATA II (SATA III compatible)] HDD 
storage – [320GB/500GB(5400rpm/7400rpm),
750GB(5400rpm)/1TB]

To check which one you are using right now type the following (Assuming you only have one SSD):

dmesg | grep -i sata | grep 'link up' | tail -n1

Or to see which are supported by your SSD type the following (Assuming the SSD is sda)

sudo hdparm -iI /dev/sda
