Although these are just fine for what they are, they don't do what RAID-5 does. RAID-10 is an acceptable substitute for RAID-5 if you have the money for the spare spindles. Promise's RAID cards are the ubiquitous "standard" these days, although you can also get motherboards that have onboard IDE RAID controllers (again, only RAID 0, 1, or 10), such as the Gigabyte GA-7DXR. Or you could use vinum(8) and use whatever IDE controller you have, and whatever RAID configuration that you want. Note, however that last I knew (Greg Lehey can update us on this), vinum(8) in RAID-5 did not work well with the fxp driver (which handles Intel EtherExpress NICs). Many here have reported data corruption with that combination, and it's apparently a *very* hard problem to reproduce "in the lab". -- Chris BeHanna Software Engineer (Remove "bogus" before responding.) behanna@bogus.zbzoom.net I was raised by a pack of wild corn dogs.
