> The drives are huge, noisy, expensive, and they have a very quick deprecation policy (new drives cant use old tapes).
Sure but old drives are widely available at low prices.
No, they are not. Specially when you have to find the one drive that will read your tapes , connect to your computer, and many other constraints that a user will have.
This is true - I got a fiber channel LTO-8 FH drive off ebay brand new in the IBM packaging for less than 750$ Tapes are 60; so breaking even against 15$ per TB HDDs is pretty fast.
