My fiancé got me the 27 iMac I7/fusion/680mx. for my birthday. (i know shes awesome) she bought it a month ago at the local apple store, and she just gave it to me today. I wish i could return it and pay the difference for the 768 ssd. i have the 768 ssd from my retina i was wondering if i should install in place of the 1TB hard drive with the blade to 2.5 sata case i got from ebay and old 3.5 bracket from a intel ssd? http://www.ebay.com/itm/160928199534?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 i would like to keep the 128 blade to run BOOTCAMP and dont wanna mess with taking my board out. Is there is any speed difference between sata and blade sata conector? i know they are both sata 3 but i wanna know if there is any loss on using the case from ebay. Thanks guys for your help!!!
