SATA Backwards compatibility

[blanco640]

I have a motherboard in my PC that is Sata 3 compatible, but the hard drive I am planning to buy and use is SATA 2.

Will I be OK to use this hard drive? I know that performance will be affected if they do work together.

Thanks.

Yes it will work. SATA III is backwards compatible with SATA II and I. Sandisk has a handy article on this:

As above. And performance won't be "affected" per say, Sata 2 is 3GBps, this is faster than a single hard drive will be anyways. You will not notice any difference.

Yes, they will work.

 

SATA is backwards and forwards compatible, which means you can plug SATA 2 in SATA 3, and also SATA 3 in SATA 2.

The only difference might be that speed of the device is limited in some cases.
