SAS Disks: The Next Generation of Something:

Serial Attached SCSI. What's the hurry?

If SAS goes commodity cheap, competing with ATA, I won't trust the pricing stability until it is a high-volume commodity used in lots and lots of PCs or workstations. So I'm in no hurry.

If SAS does go value-add, fast and reliable, competing with Fibre Channel, it's going to take time to build up the track record of quality that will allow enterprise customers to trust it with their valuable data. So again, I'm in no hurry.
