Hi. I just got another 1tb drive and I'd like to go raid-0, but I don't know the optimum stripe size OS drive is on a seperate hdd ( soon to be ssd ) and the current 1tb houses the user file, movies, etc.. I just backed up the 1 tb w/ files on it to a new 2 tb wd green. Once I establish the RAID-0 on the two 1tb drives, I'll copy over the files to the new array. Not sure if creating the array would wipe out my files, so better safe than sorry. Any advice on optimum stripe size? Also, I was curious as to whether or not the array would affect the ability to sleep the drives when not in use. Thanks.
