I've just finished installing Win 7 in my news raid 0 config. (2x500gb). I installed the o.s. on a 230gb part. and left the other 700gb for a data part. (mainly movies, music, photos, etc..) I'm about to format the 700gb partition now but I don't know what cluster size I shoud use... (4kb,16kb,32kb,64kb...). Could you guys help me to chosse which size is the best for my usage?
