Sorry a bit of dyslexia I meant DLT-S4 not SDLT-4
Here is a reference

Well, that was 404 for me but I found it eventually. I have no experience
with DLT so I can only comment on the specs. 800GB native is nice
(obviously), but filling that at "only" 60MB/s is going to take a while,
so keep your backup window in mind. LTO-3 (400GB native) is rated at
80MB/s and LTO-4 (800GB native, drives due 1H07) is rated at 120MB/s.
Also, be sure there's a good upgrade path. LTO is rather linear (erm, by
definition I guess), while DLT looks (to these unfamiliar eyes) like a bit
of a mess.
Another nice feature of LTO is the "smart" hardware compression (i.e. it
won't try to compress (and thus expand) already compressed data). Back
when I was looking, I was told that S-AIT had that as well. I'd check
that about DLT-S4 as well.
