Several vendors now have 1U boxes with 2 swappable SATA drives, and many of those vendors (e.g. supermicro) use motherboards with the ICH5 SATA chipset. We're about to buy a few too, and we intend to use the drivers in RAID0 mode. The ability to swap a drive without powering down the whole box is quite essential. Mike.
