Okay first off whats the difference between raid 0 hardware and software based...

I'm running a torrent server on a privet tracker (seedbox) so I only use cpu when I"m creating torrent files and even then only about 20-30%. So if the only performance difference is the offloading cpu calcs I might as well save 30$ a month and do software raid... I don't care if the os is raid or not.

Obviously I download at about 11MB/s and my max upload is about 55mbit (sharing a 100mbit line with another heavy bandwidth server)

Secondly will I see a big performance gain by going raid 0 (either hardware or software)

Basically going 4-6MB/s I get 100-200 cache read/s and about 40-70 disk read/s, at any time I've seeding about 15-40gb to about 100-300 peers... so yeah it's a whole bunch of random parts of a large filebase being read... so I was thinking that raid would help

Also often stoping some torrents makes the others go much faster... like It will be going 3MB/s and then I"ll stop half of them and it will shoot up to 5MB/s (closing half made the other half go 4x faster)

thx

edit: also note it has 1gb ram and I'm using all the ram thats not being used as diskcache for utorrent 1.8 beta, I"m using the beta because it allows me to disable the windows disk cache (having it on causes disk overloads while downloading at high speeds)

edit2: or would raid 1 be better than raid 0 for my purposes... ussually I'm downloading from another server so it is ussually 1 really fast thread... so write doesn't need to be improved as much as read I guess
