SATA-11 drive on older controller

[chronicle]

Hi Guys,
Just need to know whether SATA-11 drives are backwards comaptible. I've read something about this recently but now can't find it.
I'm about to replace an 80GB SATA drive with a couple of 320GB's running RAID 1. Motherboard is Intel D875PBZ which is a couple of years old and only as far as I know only supports SATA 1.
Is this going to run OK with a couple of SATA-11 drives?

Many Thanks

Rob

Try it. If it does not work, then install a controller card.

on the harddisk is a jumper that lets u choose btw. sata1 (1,5gb and sata2 3,0gb), just set it 2 1,5 and it´ll work

Yes they will work.
The reality is that even "raided" the burst read/write speed of a pair SATA300's still won't be bottle-necked by a first generation SATA150 controller.
It's been a few months since I've read any SATA reviews but unless something radical has happened since the last time I looked, even the latest and greatest only just break the 100mb/sec barrier and that is burst not sustained transfer.
All this means is that the performance difference between a pair of SATAll drives fitted to a SATA150 rather than a SATA300 controller would be barely noticeable.
In my opinion, not worth the expense of adding a SATAll controler card.

Thanks for the info guys. I've ordered the SATA 11 drives as they were only about $5 more each than the SATA drives. Slightly larger too.
Thanks again
