Why nothing newer? Because HD tech hasn't caught up to those
speeds yet! Sure, some drives are beginning to fake it with big
buffers (caches), but that only improves performance in certain
limited situations.
Actually, in the enterprise world, SCSI has given way to SAS
('Serial Attached Storage') drives
SAS is a form of SSA - which is a flavor of SCSI-3. It's ability to
talk to SATA drives is done very eligantly, by encapsulating in SCSI
packets.
heh.
Gotta love that "hum" of an array of 15Krpm drives.
It takes tintinitis to a whole new level...
