We are using Exabyte 8205XL drives and they seem to work well. We haven't had 
any
errors or file recovery problems. Performance is decent, but we do alot of 
migration
from disk pools to the tape pools to improve performance. Essentially the disk 
pool
becomes a large staging area that then feeds onto the tape. In this way you can
avoid problems with lots of small files freaking out the database.

We don't use any compression and we are fanatical about maintenance of the 
drive.
