I think it's important to realise that there are "serious" SATA disks ( eg http://www.westerndigital.com/en/products/Products.asp?DriveID=65 ) and RAID controllers (eg http://www.3ware.com/products/serial_ata9000.asp ) out there, and not write off SATA based storage as a serious option.

As you mentioned in your email reply, SATA is a consumer or workstation level hard drive interface whereas SCSI is server level.
I would only do SCSI Hardware RAID for a server of the magnitude that was being described (40+ users). But, then my background is corporate environment where I have to support 100s of users on a server. Downtime on a single server puts a negative impact on the company bottom line.
SATA drives just don't have the life cycle as SCSI drives (they are made cheaper). However, the price of SCSI and SATA are very comparable. Just buy the technology that serves the application. The fact that I can do RAID with SATA does not mean I'd bank my company on it. SCSI RAID has been around for decades. SCSI technology is proven.
