Help to buy hard drive

Hi.
This one i want:

but no calbes, another one is the same with cables and same price but the buffer memory is 16Mb instead of 32Mb like this one.

Is there a big difference?

Compare and check reviews here:

I'd get the one with the 32MB cache and the 5 years limited Parts and Labor Warranty
