USB drives are not the best for what I need.  Tapes offer more flexibility and
they are not dependent on keeping an active charge to retain memory in the
chip.

Something you might like to read - you've pointed out some pros, but here's
some cons that are worth looking at:

http://searchwincomputing.techtarget.com/tip/0,289483,sid68_gci1215078,00.html

They're not a complete backup solution. USB disk backup is best suited to an
intermediate level of backup ?- somewhere between things like System Restore on
Windows XP for quick file recovery and archival storage. With the proper
software, USB drives are suited for file recovery. With imaging software, such
as Acronis True Image or Norton Ghost, they are very good for recovering from
system crashes. But they are not a good choice for long-term storage of data.
To take care of your archival needs, you still either need to have a tape
drive, or copy your archival data, suitably pruned, onto DVDs or CDs.

They have fixed capacities. Unlike tape or DVD, where a backup can span several
tapes or disks, the capacity of a conventional external hard drive is limited.
The current maximum capacities of USB external drives ? about 500 GB ? do not
leave a lot of space for even a medium-sized server, especially when you are
doing a complete cycle of incremental and full backups. The fixed capacity also
means you're putting all your backup eggs in one basket. All your backups, no
matter how redundant or how often you do them, are going onto one drive. If it
fails, you're in trouble.

They're not cheap. The fixed capacity of external USB drives influences the
economics of using them for backup. USB is only cheap if you can fit all the
data you need to back up onto a single hard drive. What's more, if you can't
(or don't want to) handle archival backup with a built-in CD or DVD drive,
you'll have to purchase additional hardware, such as a tape drive.

Bottom line: USB hard drives are best suited for backing up fairly small
amounts of data on systems with limited connectivity, such as laptops, desktops
and small servers, where archival backup can be handled by the system's
built-in DVD or CD drive. For larger amounts of data or more sophisticated
requirements, better to use a tape drive or other system. 

...

I also can't afford a decent sized USB drive (4GB at $20-40 a pop) when I can
get tapes for $2 a pop that hold a lot more and can be used across any system
that can read an industry-standard DAT tape.  I'm not beholding to Windows
systems (remember, nearly all USB drives are formatted FAT32 and just because
other OSes can read and write to them, that doesn't mean that the drivers will
work as well as the "standard" Windows ones) with this either.

For what I need, tape works great, is very abundant and gives me piece of mind,
as well as my users.

Well, SCSI is a lot faster than USB (after all, it is a serial bus) for my
needs and it's what I know.  We use tape at work to back up our servers (and a
LOT of tape, mind you), so it's what I'm comfortable with.  As being on the
cutting edge of anything, I'm using 20+ year old technology for my BBS, so who
really cares? :)

Although I am running the BBS on a nice 1.8gHz IBM Netvista...

      Title: Emu: Livestock of the Future
 Categories: Poultry, Ostrich, Game, Australian, Texas

MMMMM----------------EMU: LIVESTOCK OF THE FUTURE---------------------
 
  Emu may be a flightless bird, but it is soaring on adventurous menus
  at restaurants and in gourmet markets all over town. Breeders of the
  native Australian bird call it the livestock of the future and are
  aggressively promoting Emu ranching. It is growing quickly: There are
  Emu raisers in 48 states, with 2,200 Emu ranchers/breaders in Texas.
  An Emu processing plant opened earlier this year in Rosebud, Texas.
  
  Emu is prized for its meat, skin, oil, eggs, feathers and even
  toenails, which are used in jewelry, fashions and crafts. An Emu hen
  can be productive for 20 years, laying 20 to 50 eggs per season.
  
  Like Ostrich, Emu's healthful qualities; low fat, low cholesterol, low
  calorie, high protein; appeal to health conscious consumers. It is 93
  percent to 97 percent fat free and has about the same cholesterol,
  fat and calories as chicken. But it doesn't taste like chicken. The
  meat is red and looks like beef. However, it costs more than most
  beef cuts, currently around $6.00 to $9.00 per pound.
  
  The industry is growing so quickly that no government grading system
  is in place yet and there are no standard names for the cuts. The
  most tender meat comes from the thigh or "fan". Because it has so
  little fat, Emu meat should not be over cooked. "Seal in the juices
  and cook it only to medium rare," advises Peg Lee, director of the
  Cooking School at Rice Epicurean Market.
  
  New Breed Emu Ranch of Austin sells an Emu cookbook for $15.00 with
  recipes from owners Lois and Rocky DeMarco. It includes everything
  from Emu stuffed mushrooms and other appetizers to main dishes,
  Tex-Mex and Italian specialties.
  
  Emu can be ground and used in burgers, stews, chili, meatloaf,
  spaghetti sauce, enchiladas, pizza and meatballs. Marinated Emu is
  tender and flavorful, although some cuts remain a little chewy,
  especially if over cooked. Many good cooks treat Emu like wild game,
  tenderizing it by pounding it out thin and marinating it.
