RE: OT Raid Setup for MP3 Server

Yes ... the thing that you're missing is a "proper" RAID 5 card is about 4 times the cost and tend not to be seen as often in the usual suppliers unless you go looking for them.

 

Most of the cheap cards support only RAID 0 or 1 and maybe 0+1 if you're lucky.

Am I missing something here, or is there a good reason not to go for a RAID 5 partition, which, has thre resilience benefits of 1+0, but with less "disk wasted" overhead.... You'd get 360Gb of usable storage instead of 240...

You will need to ensure that the RAID card that you get can support RAID
0+1 (Striping + Mirroring) - the cheap cards definitely support one *OR*
the other but not sure whether they support both at the same time.
