So, I am finally gonna be rebuiding my system soon, and this will be the first time i have tried some new to me stuff, so i am asking for some opinions and help. My system specs as far as the mobo, cpu, memory, psu etc.. will be as listed, but my case video card, hard drive set up and operating system will be upgraded thusly: 2x 300GB Vraptors in raid 0 array (this is where im mostly looking for help) used for OS and general gaming etc.. 1 750GB WD caviar black, mostly used for back-up. 1 Sapphire hd5870 Vapor-X grafx card (self explanitory...i hope) I am looking for opinions on how to do the HDD set-up, ie, do i set up the raid through my bios first, then hook up the caviar black? What are some opinions on setting stripe size? Should I partition the raid drives? Should i have a seperate partition for the os? These are mainly the questions i have, but if anyone has any other advise, things i might look out for etc.. that would be helpful. I want to do this the right way and not jack it all up, this is my first attempt at a raid, and doing things essentially from scratch. When i am done i will be sure to post some pix, i think i will be proud of this once its said and done. Also..The os will be win7 64bit (home) and the case is a silverstone FT01B. And...is there any kind of optimization guide for win7 as there is for xp? or is it too soon? Alot of questions i know... Thanks in advance!
