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.
