Upgrading SSD above 1tb

Hello there and I look forward to helping you guys out where I can, as an ex-apple hardware engineer of over 13 years standing and former accessibility developer for apple, I have serviced various apple macs from the old power pc systems to reasonabluy current systems, that is until recent machines where I no longer entertain their repair.

my question relates to a new 2015 macbook pro (ID: MacbookPro11.4/11.5) which is custom built with a 2.8 quad i7 with 16gb ram and 1tb ssd installed. This is my touring workstation as a working musician while on tour etc. I work with logic pro X and Protools HD. My current 1TB ssd is already just over half full as I use a series of sample libraries from Native Instruments, UVI, etc and the reason behind them being on the master SSD is due to performance and efficient loading within projects. Having run sample libraries off of thunderbolt external systems which can be slower and impractical to transport on the road all the time, this is how things are.

I became rather recently aware that Apple had been using Samsung PCIE SSD's for certain machines but here's the little niggle. The current spec where apple disguises itself within hardware profiler state the SSD under the terms SATA EXPRESS which is incorrect, It does however state that it is PCI architecture based.

My question to you is this, before I do the crazy thing.

Samsung have released the 960 Pro PCIE SSD card in a 2tb configuration. Will this SSD be compatible with this machine, also will I need to adapt the SSD? Any clarification would be greatly appreciated.

Many thanks and just to say this. I too support the right to repair. There is nothing worse than when a manufacturer has sole discretion of repairs and service when independent contractors are affected by unavailable schematics, diagnostics tools and further difficulties made by a manufacturer affecting how customers work with and maintain their products, in the pursuit of their own manufacturing ideals.

take care and if I can help anyone in any way with most macs, I'll try my best.
