Both of these rates are _very_ slow. I benchmarked my LTO2 drives at 27-28MB/s last week using btape. Marketing claims are for 60MB/s on 2:1 compressible data, but I believe btape's fill algorithm produces non-compressable. Even when spooling to disk and then dumping to tape, I still see rates of around 10-12Mb/s. Making up for that halving of speed, I am able to run concurrent backups, so the tape drives are more-or-less spinning all the time as various drives dump spooled data.
