If the compatability goes far enough that either kind
of
device works
with either kind of interface, then I agree, but then
I don't know quite how far it goes, but the controller
cards we use in our products all speak both SATA and
SAS.? So the drives border on interchangable.? There
are differences in the command messaging and in the
drive characteristics, but it's pretty easy to support
both.
As to the question of SATA vs IDE, I agree with
your concerns over forced obsolescence.? But as
far as classic machines go, I'm more concerned by
the dearth of 50-pin SCSI I drives, and I haven't
had very good luck with using adapters to put newer
drives on older machines.
As to FC, I will have to admit to a bit of bias.
Competing with FC pays the bills.? But even with
that bias, for communicating between a host and
a storage shelf, I have a hard time imagining a
good reason to do anything other than a light
weight storage protocol directly over Ethernet.
(And to avoid any confusion, my definition of
light weight does not include FCoE or iSCSI.)
