false in this situation. he has 4 drives so so he would have two pairs of raid 0 drives. then those two pairs would be mirrored to each other. so he really should get the performance of two drives. unless that is a single drive can read at a peak of 220mb/s. yes I have 4 of the same drives

of the two pictures below one is raid 0+1 one is raid 0. both using the same 4 drives. guess which is which

Yep, absolutely right--I (for some stupid reason) immediately assume people run RAID10 with only three drives--which would be completely stupid, and I forget about using 4 drives... Good call!

TO answer your question,

If you have the money go for 0+1 & External Controller

If you're on a budget go for 5 w/ Onboard controller

One is four drives giving you 2 disks worth of space, the other is minimum 3 drives with 2 disks worth of space. If you put four drives in RAID-5 you'd get great performance and have 3/4 of your total disk space able to be utilized vs 2/3 (or 1/2 for 0+1)
