I recently built a new desktop. Motherboard can support SATAIII 6Gb/s and I bought a 120Gb WD Green SSD (WDS120G2G0A). This SSD advertises read speed upto 545MB/s, However on HD tune tests, I barely get 150MB/s as average speed.
I am attaching basic and advanced test result here. Can you please let me know what else to look for here?
