Writing 64 Mbyte uncompresseable data:  35 sec
Estimated time to write 2 * 1024 Mbyte: 1120 sec = 0 h 18 min


2 * 1024 Mbyte in 18 minutes seems to be a little bit slow for a LTO3... :-(


This can happen you have your tapedriver in a too small fixed blocksize,
e.g. 32 bytes instead of 32 Kbytes. (Better use variable blocksize
instead of fixed blocksize anyway.)
