Re: [ARSCLIST] Hard disk drives and DAT
I'm not anyone of the folks you mention below, but we have several
LTO drives scattered across the country to support our local storage
networks. The supplemental migration cost of LTO tapes (skipping 2
generations) is very low and affordable for most of our clients. At
some point, I'm sure we'll have another high-density storage format
to use as we piggyback on the LTO roadmap until then.
I'd like to hear your thoughts more on the management of storage. Are
you referring to an OAIS compliant repository, or other methods?
Jim Lindner made a pretty good case for LTO over on the AMIA list
within the last couple of days, and they are dealing with video/ film
scan file sizes.

ONLY answer is managed and constantly migrated storage. You simply
cannot live by the old "put it on a shelf in a clean, cool room"
idea anymore. Digital storage must be in constant motion --
literally since hard drives have been known to fail or never start
up again if left idle on a shelf (ask around Hollywood, everyone
has a horror story or two). You have to plan to have a "living"
hard drive array that is redundant, preferably with a constantly
mirrored clone at a different location, and plan on swapping out
drives every XX hours of use or at worst when they inevitably fail.
There are firms that do this on an out-source basis, I think. I
believe the 90's dot-bomb term was "storage farms." Some of them
are actually located in old bomb shelters and missle bunkers.

As a short-to-medium-term storage solution--and as a part of a
more comprehensive approach--multiple HDD is the best most of us
can do at this point in time.
I prefer Maxtor and Western Digital drives, and I favor those that
come in enclosures that offer FireWire and an on/off switch. Very
vexing to have no on/off switch.
In some cases it can be more cost effective to purchase Maxtor/WD
internal drives, reliable external enclosures and build them
yourself. I've had good luck with the "Neptune" line of enclosures
from Other World Computing (http://eshop.macsales.com/shop/
firewire/add-ons-and-hubs/enclosure-kits) and have heard good
things about their "Mercury Elite" enclosures as well.
As others have mentioned, just like Coco Puffs are part of a
complete breakfast that includes toast, juice and etc., external
HDD is part of comprehensive, lower-cost storage approach that
includes optical disc and linear tape.
Not all of us can swing a RAID array. Do the best you can with
what you have.
