Hello. I have a really fast computer at home. I5 processor 16gigs of ram. I use hd tune on my hard drive and noticed its getting between 40-61 mb/s. My work compuer gets faster speeds up to 71 mbps. I have a ASRock Z77 Extreme4 ATX Intel Motherboard. I have it plugged into the intel sata3 drive like I'm supposed to. Any info on this would be appreciated because that hard drive is a major bottleneck. Windows rates my drive 5.3 and the work computer at 5.5. i have no idea why my work computer would have a faster hard drive.
