Is SCSI Dead?

I just did a drive by of Dell to see what's going on in servers these days and notice two things. First, FSB of over 1000. Whoa! I must have been sleeping when we passed 533 :).

But I also noticed that none of their base servers where running scsi drives, only SATA.

Are SATA drives now considered faster and/or more reliable than SCSI drives? The last time I looked the consensus was that they were roughly similiar in speed, but not in quality.

Most of them should have SAS drives in the customization section.

Nope, servers of quality are now using SAS (Serial Attached SCSI) drives. SATA drives are fine for desktop and even dedicated web servers, but most prefer SAS drives on web or other servers. Problem is they are expensive and not available in huge sizes compared to SATA drives.

All of Dell's server and workstation lines are available with SAS drives I believe.

SAS allows to use SATA disks too.

SCSI's only remaining strong point right now is low latency (good for DB apps), however SSDs are becoming strong contender in this area.

SCSI is a loser for sure.

SCSI market is very limited and I'd say it is shrinking - historically SCSI disks were very expensive (per GB) but they had lower latency which is good for databases, so they held up in that market. These days however SSD is providing much lower latencies and prices are falling so SCSI will soon compete with SSD rather than SATA/SAS.
