I am interested in maximizing throughput to tape. Using dd or tar I can adjust the size of blocks to to write to the tape, but what is the optimum block size for a DDS tape? Is it different for DDS, DDS2, DD3 and DDS4? I can't imagine that the disk's 512 Byte block size is the best size to write the the tape. Anybody got ideas? Thanks, Mark Szidik
