Thread Starter 
Anyone know the difference between the two?

their price difference here is less than 2 dollars.

The SATA III interface is backwards-compatible with any SATA slot. Yes, you could use a SATA III drive, but its performance will be capped at SATA II speeds.

Backward compatible.

The S-ATA III standard allows for up to 6 GBPS of transfer speed. Regular S-ATA just allows for 1.5GBPS.

Correct me if I'm wrong, but basically they're backward compatible. You just won't get to experience the full potential if you're using a SATA III HDD on a SATA motherboard, or vice versa.

Yeah only difference is transfer speeds and backwards compatibility as already stated lol.


but with no current mechanical HDD's being able to take advantage of SATA III let alone SATA II.. which is why the price difference is so minimal. SSD's are another thing though.

OTOH, with SATAIII usually comes USB3 which is more immediately useful.

You motherboard (ECS Geforce6100PM-M2) doesn't have dedicated SATA III ports. That said, you can still run SATA III HDD's by hooking them up to the SATA II ports as they are backward compatible.

If you decide to upgrade your motherboard to one with dedicated SATA III ports in the future, see this post regarding performance differences between the SATA II and SATA III interface for conventional HDD's (that are SATA III compatible).

sata III is alot faster, your board does not support it, but u can use a sata III device in a sata board, but it will not be any faster

The only devices which really suffer from a bottleneck under SATAII are higher-end SSDs such as Crucial's C300. Unless you're running one of those it is unlikely you'd see a boost in speed-all else being equal.

No HDD within my knowledge will run out of bandwidth on a SATAII connector-the bottleneck on an HDD is inside the drive on the buffer-to-disk and not the bus connector. Even Raptor HDDs to my knowledge won't be slowed down by the SATA revision.
