I found this for $409 on NewEgg and its an NVMe drive which is good. I also found an sm951 on newegg for $240 (plus the expansion card on amazon for $30). I dont really need over 1k writes so thats not an issue. Right now im looking at it like this Intel 400GB NVMe (2k Read 900M Write) = $409 Sm951 256GB ACHI (2k Read 1.5k Write) = 240+ $30 (adapter) = $270. So for $139 more i get an extra 144GB of space which would be perfect to split with bootcamp. I searched but couldnt find the answer. Does anyone know if this intel SSD (SSDPEDMW400G4R5) will be able to boot osx?
