Hi anyone. Just need a little help figuring out a cheaper raid system. Firstly, right now I have a 1tb drive (main drive for programs etc..), and I have for my 2nd drive a 2tb drive (both drives the stock Serial ATA's). I would like to add (2) more 2tb hard drives (different brand from macsales.com) to fill all bays.
Questions: If I'm going to raid 0 my 2nd 3rd and 4th drives together, do they all need to have the same capacity (eg all need to be 1tb drives or all need to be 2tb drives)?

Technically no; in reality yes. The portion of the drive used for RAID has to be the same - the excess capacity (if any) can be used elsewhere in theory but in reality it rarely happens or makes sense.
[Rob Fourchalk]"Next question: is it ok to mix with different hard drive brands together (eg Hitachi 0S02861) with my stocked hard drives?"
It's being done w/o problems (I have yet to hear of any) but rarely recommended: you may run into problems in some rare cases.
Thanks for your response Alex. Lastly, in a raid set up as I described with my number 2, 3 and 4 drive Raiding at 0, what role does my number 1 drive have in relationship to raiding 2-4 drives. Is it not included in the raid set up? Or must I include it but then it wouldn't work out as that main 1st drive is only 1tb (when I want to go with 2tb for drive 3 and 4 - drive 2 is already 2tb).
These two are exact same drives - one "retail" (in a box), the other one "bare". For some inexplicable reason (anyone?) that I haven't googled yet, the retail one sells for less than the bare one. Go with the cheaper one.
