Anyone here have experience with RAID

The only thing i can not do without in all of my data, is my personal music collection...which is why its mirrored on 4 different disks, When my last drive failed i only had a partial backup and i was devastated so now i back it up at multiple sources

Thank you all for the help, I've got a WAY better understanding of RAID now, and I may be re-considering the actions i should take.

I think why I'm so adamant for a RAID array is because of the safety net they provide, especially RAID 5, I don't have enough disks to do RAID 0+1, so i figured 5 was a good compromise

I don't think i can really justify backing up all of my data to DVD's, that'd be close to 100 DL DVD's which cost close to 3$ a disc

My data mainly consists of TV shows that I rip from my tuner card and then cut out the commercials so they have a personal attachment to them, and the rest is movies and games and applications that i use from time to time

I can lose all of the data and still survive without it, but to me its nice to have a wide collection of multimedia to choose from when the time strikes

Once again, thanks to everybody for the big help this thread has provided me
