If you're just talking about audio, then RAID-5 would seem a better choice. You get much higher effective space utilisation (75-90% rather than 50%) and even the degraded bandwidth is plenty for serving a couple of audio streams. > and upto half the drives in the array can fail without anything but >speed being degraded. Normally, you replace a drive soon after it fails. The risks of a second drive failing should be fairly low. Note that you should try to get drives from different batches - all vendors have the occasional bad batch and you don't want all your drives to die at once. >RAID5 sacrifices write speed and redundancy for the sake of space.

Redundancy may or may not be an issue - it depends how quickly a failed drive can be replaced and whether the risk of one of the other drives failing during this period is acceptable. The main advantage of RAID-5 is increased space - and this would seem to be an important issue. -- Peter Jeremy _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
