SATA III HDD on SATA II Motherboard

[JBails]

I know that SATA III is backwards compatible to SATA 1.5 so no worries there, but my questing is:

Will a SATA III HDD on a SATA II motherboard be quicker than a SATA II HDD on that same motherboard, or does it not matter since it's limited to SATA II speeds?

doesn't matter, mechanical hard drives cannot saturate sata speeds. if this was ssd, then it's a different story.

Sata III HDDs sustained throughput is the same for being on a sata II or a sata III port. Ther is ONLY one parameter that is improved by being on a Sata III port, and that is the very short burst speed.

Case inpoint compare the Sata II samsung F3 on a sata II port and a Sata III WD Black on a sata III port, Bet you would not be able to tell which is which in real day-2-day usage.
Note I have both of the above configurations.
