SATA vs. SCSI -- SCSI is theoretically faster, although many say that the practical difference is minimal. SCSI is theoretically more reliable, but with 2 SATA drives in RAID redundant configuration, this is a very minor issue?
SCSI performance is better in practice too, especially when you have multiple hard disks. But the work those boxes will have to do (load balancers, squid, web serving, mail server) does not seem HD intensive, if they have enough RAM.
SCSI disks are usually more reliable, simply because disk manufacturers test them more and use higher quality components (hence the bigger price). If our boxes are redundant, and each box has a RAID 1 array, I don't think that going with IDE/SATA is a problem.
