Is there anyone aware of the most efficient way to upgrade internal storage on a Mac Pro Late 2013? It seems a few user have been able to upgrade their builds over time, although considering technical progress there are quite a few different approaches. I was wondering, what would be the most efficient way (cost- & speed wise) as of late 2017. Option A: Buy a used Flash module on eBay. (Which one? Is there a compatibility list somewhere?) MZ-JPU512T/06 MZ-JPU512T ... Option B: OWC Aurora SSD Module Option C: Transcend JetDrive 820 Series Option D: Some kind of "12+16Pin Adapter M.2" allowing to make use of cheaper PC-Components Thanks!
