Data point here: We have a Linux software RAID quite close to the setup you describe, with an onboard Adaptec controller and four 146GB 10000rpm disks, and we get about 65MB/sec sustained when writing to an ext3 filesystem (actually, when wgetting a file off the gigabit LAN :-) ). I haven't tested reading, though. /* Steinar */ -- Homepage: http://www.sesse.net/ ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
