Does 6gb/s matter or 3gb/s more than enough for a storage device?

[asalikus]

I wonder if it's worth it or not to have a 6gb/s bandwidth on a HDD?

Will a HDD actually get to speeds greater than 3gb/s? No. The added speed capability of sata 3 is not going to help a single HDD. If you had multiple HDD's along with maybe a SSD, then you could see the need for sata 3 as you could move data to all at the same time.

It is much more important when you're looking at SSD - you will see a significant difference in SATAIII drives over SATAII. Unless you're dealing with WD's Raptors, you won't see a substantial difference in performance

So it doesn't matter much on HDD, if it does by how much? 1MB/s?
