Hard drive not running at 6Gb/s

Last response: in Storage

Hard drives can be SATA 6Gb/s compatible, not 6Gb/s capable.

No hard drive can spin fast enough to achieve SATA 6Gb/s speeds.

Your drive has a buffer (16MB, or 32MB, or 64MB) which briefly transfers data at 6Gb/ speeds, but that's it.

What's the model of your drive?

It's the WD1002FAEX drive. I have it hooked up to a SATA 6Gb/s port.

Yes, it is. Some faster HDDs (like the Seagate Barracuda) can get up to 210MB/s, which is in the SATA 2 (3Gb/s) speed range.


Thanks for your help. What is the point in 6Gb compatibility if it doesn't come close... I have a lot to learn regarding hard drives.
