Now I've got some reading to do to decide on attaching the SATA drives to SATA or RAID...
(from other thread):
I've never worked with RAID before, and wondered how to configure my two 80GB SATA drives for maximum gaming and music playing performance. I'll most likely have one drive mirror the other in order to keep a complete system backup should the primary drive fail. -Mental_Myopia
Well I don't do RAID, but to do RAID1, which is what you are talking about, it will have to be off the Promise if you use this mobo. The Promise is on your PCI bus. Which will share bus bandwidth with your soundcard (which you need, for "maximum music playing performance"). I'm overlooking some details like where the music buffering occurs, but in terms of "maximum... performance", this isn't going to quite be it.
Further, it occurs to me that because all data has to be written to disk twice, I can't see how this can be maximum performance either. In my mind, RAID1 gives you the benefit of data redundancy but like everything else it isn't free... you pay some performance somewhere.
While I whole heartedly agree that backups are a good thing, I don't expect my brand new HDD's to die any time relatively soon, so I don't want to pay performance penalties from now until then, on every single disk access. Rather, my plan is to buy an external tape backup device ($$$$!) and do regular backups... unfortunately with me, regular has never been regular enough
in the past, but that's the plan anyway. I've got the SCSI-U160 card, now I just need the drive.
Hope this helps,
if not then start a RAID-1 thread to get some duscussions going with folks who really know.
