As Paul says, this will depend as much on your data as on your hardware.
 Using 3590E tape drives, yesterday we got rates of 1.6MB/s to 55.4MB/s
as reported by Servergraph/TSM on our 5 tape to tape storage pool
copies; the median was 27.4MB/s.  The rates on our 8 tape storage pool
reclaims last night ranged from 2.1MB/s to 25.1MB/s with a median of
8.2MB/s.
