How do i find at what speed my Hard drive/SSD is?

Solution
SATA3 port on motherboard and SATA-3 SSD then 6GB/s
SATA3 port on motherboard and SATA-2 SSD then 3GB/s
SATA2 port on motherboard and SATA-3 SSD then 3GB/s, but your shouldn't see any noticeable difference to a SATA-3 port, unless you use a high end SSD.
use CrystalDisk to test the speed of your ssd and compare it to the specification claimed by the manufacturer.
Sata3 should have a peak of about 550mb/s
Sata2 should have a peak about 150mb/s.
