[ILUG] Cheap large capacity tape drives

[Damien Gill]

What about one of the new DDS4 dat drives 20/40gb on a dat, not sure of the
cost but its bound to be less than DLT.

Did I say you did? ;-)

Reading over your post, you didn't say this; However...

...in which you seem to be saying that the cartridges for a cheap drive
are relatively expensive compared to the cartridges for an expensive
drive. (DLT, I assumed). Which would imply that the cartridges for an
expensive drive (ie. DLT cartridges) are relatively cheap compared to
the cartridges for a cheap drive. Which is just a stone's throw away
from calling DLT cheap. A bit tenuous, perhaps...

Anyway, *are* DLT cartridges cheaper per megabyte than cartridges for
(say) travans...?  (clickety click)  Wow! They are. Best part of twenty
quid for a 4GB/8GB travan cartridge. That'd be two hundred quid for
40GB/80GB, which compares badly to the sixty-odd quid a 35/70GB or
a 40/80GB compatible DLT tape costs. (IV? V?)

Aiee! That's awful. :-(

Sorry, I was stuck in the "I've lots of data I want to take home" mentality.

All the best,
