>Description:
Two BusLogic BT-958 controllers, each with 4 Seagate ST34371 wide
drives. Reads go at ~7MB/s on the outer zones. Writes go no faster
than 60KB/s. I'm not kidding.
System: 512MB primary memory 200Mhz PPro SuperMicro P6NDH motherboard.
BusLogics on secondary PCI bus.
Workaround was to put an Adaptec 3940 in place. Drives worked fine.
