just got done installing a amazon optibay. it has all positive reviews and was only 20 bucks shipped. it fit like a charm, although was actually a tad tight going in. i had a few close calls with almost losing some screws but all went well. not too hard as long as your careful and have proper lighting. sucks though because I'm going to have to do the job again pretty soon when i get a new HDD. right now i just threw in my 250gb 5400rpm toshiba drive from a 2009-2010 macbook to hold my music and such. i don't really want to mess with it again, but i guess i know what I'm doing now so it shouldn't be as bad. so far the 5400 rpm drive is silent, heat, and vibration free in the fake optibay. any recommendations for the optibay drive? like power settings/sleep settings and what have you? also what folders are you guys keeping on the ssd and what on the hdd? like for iTunes do i keep everything but my actual music files on the ssd and the music files on the hdd? what about for iPhoto and such. any help is appreciated.
