Hey guys, my main drive- intel 520 series 128gb, is running at half the speed of my secondary SSD, Crucial MX500.
Have enabled AHCI. Is there any reputable SSD software I could run to give everyone a better idea of my issue?
Thanks a lot, MM

Both drives are plugged into the only two available sata 3 ports. Motherboard limitations? Throwing this out there, Can both SATA3 ports run at full speed or is there a hidden limitation?
