Non-Apple SSD blade in iMac 21.5" Late 2013 PCIe slot?
I've made a low-cost SSD upgrade to a MacBook Air 11" Mid 2012 (MD224) from 128 GB factory default to 500 GB Samsung 850 Evo M.2 NGFF SSD in the past, using this cheap M.2 NGFF SSD to 18+8pin SSD Adapter. Works like charm and much, much cheaper than a genuine Apple SSD module.
I'm trying to figure out if there’s such a low-cost SSD upgrade path using the PCIe slot in an iMac 21.5" Late 2013 (EMC 2638; Model ID iMac14,3) as well. I'm aware of the option the replace the 2.5" HDD with an 2.5" SSD, but I'd like to keep the internal 1TB HDD and add a 500 GB SSD blade module to the PCIe slot. Unfortunately the genuine ones from Apple are totally overpriced.
Anyone knows of a low-cost adapter for using generic SSD blades in the said iMac, such as the above Samsung Evo 850 M.2 SSD or another PCIe-based solution other than going for a used genuine Apple SSD blade?
