Hey there..
I was wondering if anyone could share experiences they have had with the Intel ICH10R SATA controller? I tried looking around but all I could find were RAID references, I have no interest in using the RAID functionality just basic SATA JBOD. Wondering if there are any gotchas for performance, drivers, quality etc.
I normally don't touch anything that is not hardware RAID though this is a special project.. And even if I get demo gear I won't have enough time to put it through real paces(likely need weeks) before a decision needs to be made.
I don't see anything that is causing alarm but just curious if anyone else has experiences.
thanks

jsut put the bios into sata or ata mode and not raid..then the raid functionality is zero..:)

even when its enabled, the raid functionaliy of the ICH??R chips is zero. :) "enabling RAID" in the BIOS simply sets a bit in the chip thats write-once (once its set, it can't be reset short of a full chip reset), this does two things.
A) it changes the PCI DEVICE_ID of the chip so it requires different drivers, B) it tells the BIOS and drivers that they should implement Intel Matrix aka fake raid rather than standard SATA JBOD.
thats *ALL* it does in hardware. nada else.

i understand that..but he doesn't want the fakeriad of the bios emulation or bit flip or whatever active so my comments about how to avoid it are accurate and stand as accurate.

if anyone else has experiences.
I have the GA EP45-ud3r MB with this north bridge. Mine has 3 separate Bios entries for ahci, raid, and jmicron.
IIRC C5.4 has drivers for all. The worst thing you can do is install with the functionality off in the bios. Turn them all on, install, then decide if you want to tweek.
I never ran JBOD, but did try RAID0 and it was flawless. Dmraid handled it.
