Raid0 or Raid5 for network to disk backup (Gigabit)?

Anyone have any thoughts on which is going to give me better write

raid1, redundant..

But I'm assuming when I backup my servers to (this backup server)
across the gigabit network, my write speeds would max out at say 60 MB/
s wouldnt they?

I think right now on Raid5, sataII, i'm getting a write speed of 57 MB/
s (bypassing windows cache, using SIsandra to benchmark).. if you dont
bypass the windows cache this becomes more like 38 MB/s..

Any thoughts?


two disk raid0 with write cache turned on. better read/write
performance all around and twice the disk space. run the
backup machine with a UPS power supply

so what if it (raid0) fails every few years? it's a minor backup
machine and odds are that it won't be the end of the world

if the backup is not "minor" (meaning totally critical),
then go with slower raid5 (or something similar)
