I just bought a new mobo with sata III!and know i willing to buy a new hard disk!I was looking for western digiral caviar black!
Now, Sata II vs Sata III! has any difference?Or it is all marketing ?I would appreciate if you could answer my thread!
Have any difference in perfomance?
AKAIK there are NO hard drives that can use the increased speed of SATA III. However, SATA III is ideally suited to SSD's which are REALLY fast (and more expensive). So if you're shopping for WD blacks and worried about SATA II, stop worrying. There are no super-fast blacks about to appear on the market that might exceed the existing SATA II speeds.
Chris1984, The WD SATA III drives have a 64 MB cache vs 32 MB on the SATA II drives. The heads and platters might be basically the same but I would think the 2X bigger Cache might inprove performanc/xfer rates. Sensible???
I also read on Hard Forum, they did a nice USB & 6GB/s tests.
Sata 6GB/s WD Black w/64mb cache only showed improvement in the Burst peed test!
So @ least there is a little benefit of WD Black on the new SATA speed!
