I have both technology.  I was using both 3590 and 3592 in a 3494
library and have since move to a 3584 library with 3592 and LTO4.
Performance wise the LTO4 are a screamer in backup while the 3592
definitely are more rugged.  800 GB does not sound like a lot of data
per night.

IBM just announce their rack mount libraries with LTO4 drive
capabilities.

We are talking about 800 GB per tape vs. 60 GB possible with extended
length 3590-H1A models
