It isn't. Seagate has a 182MB SCSI disk. Although it's only 7200RPM. (models
ST1181677LCV and LWV)
The argument is that
certain technologies while not necessary for you may be necessary for
your neighboor, and shouldn't be discounted.
I figured you'd get the fact that I was continuing your line of thought on
that...
SATA seems like a good inside the box disk option. Cabling is certainly a big
plus, although I question the need for Yet Another Power Connector. For
outside the box and really big arrays fibre channel is the clear winner in
terms of performance and capacity, with arrays being able to be split amongst
different towns if need be (given that they're within a few km of each
other). But SCSI still has its advantages for many things.
