Of course, the new DVD's may store most of your data or
programs depending on what you currently have or will have --
DVD rewritables that is, to keep ongoing cost down.

DVD's are too small and too slow. I just did a four-day event and I've got
about 50GB or raw files. I'm not going to 1) put this on many DVDs or 2)
write that on a couple HD DVD's and wait hours and hours to burn and have
crap read speed.

Nope, I backup to external hard drives, two of them. And I can work from
them directly. I now own about ten external USB HD's.

Not really. DVDs are not too small and too slow. It's more
accurate to say that they may be too small and too slow for you, but
probably entirely adequate for most people. This reply, btw isn't
really intended to be critical of your method so much as giving me
an opportunity to discuss Blockbuster's just announced decision to
back the Blu-Ray disc format.

Having said that, your backup needs are not at all typical, and
from what you've said so far, while you're archiving something,
you're not really performing true backups, unless you have one copy
of all of your files saved on five of the hard drives and another
copy on the remaining five hard drives. If your business couldn't
survive the loss of your files due to theft, fire or some other
disaster, complete archive copies stored at different locations
would be wise, and high capacity tapes might be more practical than
using hard drives.

But before very long Blu-Ray discs may be a practical alternative.
I say this because just this morning I heard a business news item
indicating that Blu-Ray just made a substantial move to become the
standard format eclipsing HD-DVD, with Blockbuster's decision to
back the Blu-Ray format. They made this decision because they found
that in a study of rentals of Blu-Ray and HD-DVD titles in 250 of
their stores, more than 70% were Blu-Ray. They've decided to only
stock Blu-Ray titles in their 1450 US stores. (Another report says,
however, that the HD-DVD titles will continue to be available in the
250 stores where they're currently being rented). What's more,
Microsoft also admitted that their Xbox 360 may eventually support
Blu-Ray discs which have a 50GB capacity per dual layer disc, and
multilayer discs will eventually up that to 100GB to 200GB/disc.

The initial Blu-Ray 2x drives have data rates of 72Mbps but
several 4x/144Mbps drives should be available shortly, and
eventually 8x/288Mbps drives. One of the 4x drives (Benq) can burn
the 50GB dual layer discs, so burning 50GB should take about 45
minutes, so you shouldn't have to "wait hours and hours to burn".
If you need to use two discs to hold the entire 60GB, you may still
get all of the files backed up in under an hour.

This can allow you to turn your 12 hard drives into two or three
RAID arrays (speeding up editing operations) and make backups onto
Blu-Ray discs or high capacity tapes, so you'll be able to make
multiple relatively inexpensive backup copies (when the writeable
disc prices eventually fall). If your business would consider the
loss of your current drives due to fire, theft or some other
disaster to be intolerable, having archives in different locations
would just be good business practice. This might be impractical to
do right now, but in a year or three . . .
