Hard drive question- for a new cpu

Last response: in Components

I'm looking to buy a hard drive for my new low budget cpu build.

The two I am choosing from are both Seagate with the same specs except one is 3gbs and the other is 6gbs. What does this rate refer to and how big of a difference is this in terms of performance? :) 

Best solution

That refers to the maximum theoretical bandwidth per way between the hard drive and the SATA controller on the chipset. It doesn't really matter for hard drives, but the 6Gb/s model might have something such as better cache or slightly more optimized platters and have higher performance as a result of that insteda of the faster SATA interface. Even the fastest hard drive can't fill SATA 3Gb/s speeds in continuous throughput, so like I said, the SATA version is less important than the other differences that it tends to be included with.

It can help the SRAM cache performance, but that's probably not be a big difference in average system performance at all.
