Re: Tape suggestions

thanks for the tips but DAT drives are way beyond what I plan to spend (I
really like DAT drives but I can't justify one for what I'll be using it).
Just to compare prices, I called some stores in town today and I got these
prices:
- HP/Colorado T4000s (4GB raw, 8GB compressed - Travan TR4 with SCSI-2
interface): $470 - $550 internal (about 100 more for external)
- Conner/Seagate TTR8000R (same Travan TR4 with either SCSI-2 or IDE
interface): $525 internal.

A TR4 cartridge costs around $50 so a drive + 16GB tape (which is more than
I'll need for the next 12months) = $700. And DAT solutions will probably start
at at least 50% over that amount (though the media is a lot cheaper per GB).

I checked the Exabyte Eagle webpage and they are Travan drives (like the ones
above) and there no SCSI versions (only floppy and IDE).
