Heh, well there's this:

If you have a laptop with only one M.2 slot and you really need 3500 MB/s speeds and you really need 4TB and it's worth spending $700 to do that, then there it is!
That would let you work with over 12,152 simultaneous tracks of 24/96 audio FYI.
I'd probably look to a different setup (eg. desktop build) if I had to shuttle that kind of data around and try not to rely on an expensive M.2 drive solution.
Otherwise I could snipe up a used i7 Macbook Pro on Ebay and throw a 1 or 2TB SATA SSD into it for less than the cost of that 4TB M.2 drive. (Assuming 600 MB/s covers the I/O needs. So, you'd be restricted to just over 1000 simultaneous tracks of 24/96 audio.)
FYI, take a careful look at exactly which version of M.2 drive your machine supports! There are at least 12 variants at this time! Some of them even have the same sockets! Note that there are pci card SSDs like this that actually use a SATA controller. The M.2 devices are about the furthest thing from a standardized item I've ever seen.
