Hey guys! Has anybody added a blade SSD to a late 2012 iMac 27"? I know Apple used a custom connector for a SATA 6GB/s SSD. As far as I know there are four options for to add a SSD, but I just found a confirmation for two of them. 1. Plugged rMBP 10,2 SSD Getting a plugged SSD from a Mid 2012 or Early 2013 retina Macbook Pro should work fine. There are always a few available on eBay. 2. MaxConnect MaxUpgrades has two kind of products, a 2,5"-Upgrade and a Blade-Upgrade. 3. Transcend and OWC Transcend has a series for the rMBP called JetDrive and the OWC Aura 6G. Both are made for the rMBP and I don't have any information whether they are working in the iMac. 4. mSATA or M.2 to rMBP adapter There are a few adapter for mSATA to rMBP and m.2 to rMPB. I don't know, whether theses are going to work or not either. The mSATA to rMBP looks a little like the MacUpgrades, but maybe there is some magic in that one I don't know about. I'd like to ask you, how did you upgrade your late 2012 iMac 27? Which way did you use? I'd really appreciate all your feedback regarding this topic. Thank you! Cromb PS: I know it's a tough job to add the SSD: removing the screen and the mainboard is tricky, so please do not comment on this. Thank you!
