Sata III vs Sata II

GSquadron · Apr 24, 2010

Hello guys!
I want to buy a new hdd for my computer, but i dont know what to buy...
I saw in an online retailer a sata III hdd 1TB:

And this one which is Sata II:
http://www.e-shop.gr/show_per.phtml...ERN-DIGITAL-1TB-WD1001FALS-CAVIAR-BLACK-SATA2
Which one to buy?
My mobo only supports Sata II.

Get the cheapest.
No real difference on mechanical drives, maybe burst rate but thats it.
Sata III is backward compatible and should work on your board.

The sata III has 64mb buffer, instead of 32mb of sata II. Does that mean that it is faster?

Kreij · Apr 24, 2010

Only if it needs it. If the HD can keep the amount buffered under 32MB, it will never use the rest.

if its the WD drives with sata III and 64MB cache, dont use them if you're running windows XP

From everything I have found *not tested personally but will be soon* SataIII drives on SataIII controllers are actually "SLOWER" than SataII drives on SataII controllers do to overhead and the drives not being any faster to use that extra bandwidth of the port.

Is it all compatible? Meaning can I use a III drive in a II port board and II drive in a III port board?

yes, they slow down to match the highest common denomimator.

so, if you have two sIII ports, two SSD's, one of which is a crucial sIII, the other a ocz vertex, the crucial will be throttled back to sII speeds? Not talking about raid...

its on a per-port basis.

sata III device on SATA III port = sata III speeds.

sata II device on SATA III port = sata II speeds
