writing to tapes

For DDSX, the block size is set by the manufacturer.  I've found that
using '0' (for variable block size) works best if you've not
standardized on a single brand and type of media.

Subject: writing to tapes



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
