Will ICH9R RAID5 work with 3TB Hitachi SATA HDs?

[VirtualLarry]

I know that the ICH9R is an older chipset, and thus, the BIOS extension for RAID is going to be older. I know that you need UEFI for BOOTING a 3TB HD, but supposedly, with Win7's support of GPT, you can run 3TB or larger HDs as DATA drives.

Can you use 3TB HDs, in a RAID5 config, as a giant DATA drive? Will the Intel ICH9R RAID extension BIOS allow that? The Hitachi drives are specifically not the 4KB Advanced Format drives, they instead use 64-bit LBA or whatever it's called, with 512byte sectors.

I was hoping, although I don't want to splash out the money for more HDs if it doesn't, that this would work.

I guess I could try buying two 3TB Hitachi drives, and set them up as a RAID0, and then see if I can use them in Win7 as a data-only drive with GPT, that would tell me if the RAID extension BIOS handles 3TB drives OK.

The drive I was thinking of getting:

no it will fail. RAID-5 on ich anything is a bad idea. raid-0 works, raid-1 may work with TLER/CER enterprise drives. Otherwise stick to jbod or WHS style.

There is a reason many oem's removed raid-5 from ich chipset roms. its a recipe for disaster.

Raid-5 without a battery/flash back write cache is going to suck big ones on write speed. 30mb/s with 300mb/s read with 3 drives 7200rpm. 30% slower than 1 5400rpm at writing with no write cache as raid-5 requires a read/write/read for every operation.

Raid-5 on a dedicated storage box with a battery/flashbacked write RAID controller cache/good ups (with automated shutdown) and RE4 WD drives - probably good to go , but i'd still spend a few bucks more and rock raid-10 - it gets rid of the raid-5 holes for a nominal cost and you get 2 drive failure without any checksum/crc computation
