Serial ATA not for primary storage?

You know, we've been living in this world where people have inflated expectations. SCSI vs. S-ATA is one of those cases. For most people, most companies, most data... S-ATA is good enough to handle our data needs. So why do vendors keep telling me "S-ATA is not good enough for primary storage". The fact is that reliability and MTBF are approaching SCSI, and while performance isn't there, with parellelized RAID is that such a big deal? I think not.

So take the talk about SCSI being "enterprise class" compared to S-ATA with a grain of salt, and do a careful cost comparison. Chances are that you, like me, will decide that for most applications S-ATA is the right choice.
