Generally we have not  had any major problems with LTO drives ( more than
one year), we have 12 LTO drives in 3584 IBM library , using Netbackup 3.4
and also SSO . at the beginning we had some minor issues mostly because Tape
library and drives have 2 different firm ware that need to be updated .
Drive's down and read errors are because of old firmware . we got about
10-31 MB/s for each drives and we backup oracle database about 1GB less than
a minute in average .
