For example, SONY SDT-5200. Very good drive. BTW, I think hardware compression
isn't important. The compression is usually not very good (like w/ compress(1)),
and for DDS-2 I/O rates this can be done on the host CPU with negligible
additional load. The only drawback of drives without HW compression is that you
can't read tapes written with the compression enabled.
