Currently I have a boot raid0 pair set up in bays 2+3 of my MP2.66. Can I move that pair to bays 1+2? Does the order of the pair need to be maintained, i.e. the order of the bays and drives or does the OS figure out which is the first part of the stripe, so I could install the pair on 1+4 or 4+2, etc.? Also are all the SATA channels, including the 2 behind the fans totally independent and at 3 Gb/s speed so it doesn't matter which channel any one physical drive is connected to?

In the end, what I want to know is if it matters where I put my fastest drives (Raptors) versus my slower ones.

Well, I needed to install new drives so I just tried moving the striped pair and it worked fine (2+3 to 1+2). I did not try to swap the left right order, but I suspect that it doesn't matter, the OS might keep track of the HD's IDs and figure out which drive is in which place.

good to know

I am not sure why you didn't get any response the first time around, but the answer is, as you found out, that it makes no difference where on the bus the drives are nor what order they are in.

Sherman,
Thanks for echoing what I discovered: that the buses are indeed totally independent and it makes no difference where the physical drives go, even with striped RAIDs. A very convenient feature!

Just make sure with a RAID 0 that you have a good backup scheme!
