sorry to be blunt, which is better out of the above?
many thanks
many thanks

yes a 6 is higher than a 3 but which is better?
Did you mean SATA 3Gbps vs 6Gbps?
If so, then for a mechanical HDD, it makes no difference whatsoever. For an SSD on the other hand, you are opened up to much higher read and write speeds. SATAII or SATA 3Gbps is limited to speeds of 300Mbps.

In practice it's around 300MB(ytes)ps for SATA 2 and 600MB(ytes)ps for SATA 3.

i was refuring to ssd's that say sata III and others that say sata 6Gbps i just wanted to know the difference, thankyou for all your answers

that is what i was trying to understand and did not know so my question was right!

They are exactly the same. SATAIII is the 3rd SATA revision, and 6Gps is its speed.
So when i'm looking to replace my 500GB HDD for one with a larger volume, are you saying there isn't much point in buying a SATA III one over a SATA II one??
My Mobo supports SATA III, and i'm using an SSD (60GB vertex 2) as my boot drive but I need more storage space. I was looking at the WD 2TB drive, the SATA III is another £5 over the SATA II.

With mechanical hard drives, they have updated them to sata 3 so they can charge more, not because they are any better/faster
With ssd's you should check the speeds it is rated at, if it is higher than sata 2 can handle (~300mbps) you need to put it in a sata 3 port for optimum performance
.Can you elaborate a little more on this?? If you're making reference to mechanical drives, then it seems to contradict what others are saying...
Try reading the rest of the thread.
SATA 3 6Gbps is only better if you have a fast SSD which can make use of it.
For mechanical HDD's SATA 3 offers no more speed than SATA 2.
Uhm, is this still the case? Seems spurious to advertise a HDD as "6Gbps" if mechanical HDDs cannot achieve that. I can't believe they would charge you extra for something for which you receive no benefit.
Anyway, I have bought a SATA III drive (WD Caviar Black 1TB) and then just realised that I have got a SATA II motherboard. I was gonna ask what noticeable performance difference I will notice, e.g. will every file transfer be half as fast? But this thread suggests that I wouldn't have got a difference from SATA III even if I did have a SATA III capable motherboard.
Glad I didn't get an SSD though! Think I will wait until I upgrade my mobo for that, which sadly could be some time.
