consumer SATA drives has been incredibly dismal, with ~40 of them in

surprised if one or both of the drives was bad right out of the box.

makes backing up 300GB+ of data easy. Everything that's capable of
doing this is in the tens of thousands of US dollars, if not more. Am I
going to sit around once a week backing up a terabyte of data to ~120
dual-layer 8.5GB DVDs? Nope. The closest thing out there right now is

Which are only available in write-once in dual-layer so you would soon have
a landfill worth of DVDs.

A new IOMega REV (which includes one 70GB disk) costs US$600 MSRP. You
read that right.

Pff. Find a pre-owned SuperDLT or LTO drive? Not the cheapest I guess,
but dual-layer DVDs are not a solution IMHO.

Or get a Blu-ray disk? Also still $$

I'm using an LTO2 drive myself.

* SCSI is outrageously expensive even in 2007. I have yet to see any
shred of justification for why SCSI costs so much *even today*. It
costs only a smidgen less than it did 15 years ago.


For non-silly benchmarks, SCSI/SAS/FC is still far superior to SATA,
and that is what you as the consumer are paying for. But without those
high margins, you as the consumer won't have SATA either, at least not
in the current business model. How do you think that R&D gets funded at
drive companies? It's definitely not from the razor-thin margins that
SATA has. Companies like WD make it work by having a very diverse
business to fund SATA, but that's really no different than having
SCSI/SAS/FC to fund SATA (though maybe less volatile).

* SCSI is on its way out. Seagate recently announced that
they'll no longer be supporting SCSI products, possibly by the end of
next year:

Yes, Seagate might be saying this, and I won't comment on the wisdom of
it, other than to say that SAS/FC is not dead despite what Seagate
wishes to do. In the future flash storage might ultimately overtake and
replace platter storage, but that future has not yet arrived.


"Seagate has announced that by next year they will no longer be
supporting SCSI product and will be moving customers to the SATA
interface."

I imagine this is meant to read as: parallel SCSI, as opposed to SAS.
SAS is very much alive.


If Seagate is plotting a course to be a SATA-only company, I'm not
terribly surprised. I would be saddened, though, and I feel sorry for
my friends and neighbors who are currently Seagate employees.
