Hi all,
I'm getting 4 x 250GB Western Digital WD2500YD SATA2 hard discs and was wondering which RAID level to use.
0+1 will give me just under 500GB to play with - plenty for now, but I was wondering which will give me the most SPEED?
I realize Raid 0 is faster than Raid 5 generally, but since this configuration will have a stripe of only two discs, mirrored, will it actually be slower than Raid 5 which will have FOUR discs striped? Even with the parity overhead, surely reading from/writing to four discs simultaneously will be quicker than just two?
FYI I'll be using the nVidia Raid controller on a Gigabyte K8N51GMF-9 mainboard.
I'm interested to hear ppl's opinions on this.
Thanks!
