Just for reference: i get 330 KB/s (only) from the 3401 on a 486/33 with a Buslogic BT472A (EISA) controller (raw `dd' throughput). The controller is known to get about 5 MB/s from the Seagate Hawk that's also in the machine. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
