Hello, All. My name is Will. I'M running a mid 2014 15" Retina MacBook Pro for audio production. I have a rather complicated (not really when I explain below) setup I'm trying to acheive. For starters, all of my AUDIO gear is RACK mounted, and my main task at hand is to upgrade my external storage options WHILE upgrading my internal SSD for speed if possible. I bought this. http://www.sonnettech.com/product/echoexpress3r.html Its a rack to hold PCIe SSDs, or to house my future audio upgrades. HERES WHAT IM LOOKING AT NOW for the internal SSD of my MacBook Pro. http://store.mcetech.com/mm/merchant...PCIESSD-L13M14 It can/will replace the internal SSD of my computer, and I can use the OLD SSD (512gb) in the Rack PCIe Expansion bay I showed above, via an adapter of sorts for the PCIe bays. MY QUESTION!!! IS THAT THE FASTEST MB/S I CAN GO WITH?! (1400/1100 mb/s) Ive seen a few guys take the 1TB MacBook pro/ MacPro SSD, and install it. Its called (SSUBX I believe??? Also seen SSAUX???) Many different numbers too. 0A3, 0A4, 0A6 etc. Apparently it was a factory MacBook option, and also came in the Mac Pro (Trash Can) Cylinder. http://www.ebay.com/itm/OEM-Apple-Sa...05874434&rt=nc from what I've read, it opens up 2 more lanes, making it 4 Lanes total AKA twice as fast. This SAMSUNG NVMe 960 PRO IS STUPID FAST THOUGH!!! Some 3500 mb/s!!! http://www.samsung.com/us/computing/...b-mz-v6p1t0bw/ HOWEVER, I cannot find a single place saying that I can get it to work INSIDE my MacBook pro, and be the fastest option, AND also reliable. Toms Hardware had an article aout installing drivers for it, because it is NVMe, yet I've also seen where with OS X Sierra, apple now supports NVME...???? Heres the Toms Hardware NVMe Article https://www.tonymacx86.com/threads/o...leased.181387/ Ultimately, Im confused as to why I cannot use the fastest thing I've found (The Samsung NVMe) without some hacky-driver install, when I've seen where OS X now supports it. Whats my fastest/best option? I have one shot at doing this, price and time wise. The MCE seems like its plug and play, fast, and is recognized right away as internal SSD and is TRIM supported, but Samsung is WAY faster, provided I can get it to work.. Maybe something I haven't listed, or found yet..? THANKS in advance!!!
