If not, then you're mostly out of luck, but you can try if you manage to source it. And find some datasheets. And have a driver for it. And...
On a more serious note: It would be very nice, if it was possible to design a board with components like this, but it is way to hard and needs way too much equipment and experience to do right.
What caught my eye in this SSD package is a low ball count, so it might be potentially suitable for DIY even without an expensive hardware. If it's possible to route it on 4 layers without too many small vias it might be a game changer.
On the other hand, 1,500 MB/s data and PCIe are quite serious levels of performance by most DIY project standards. :)
EDIT: actually, no, it's a single lane PCIe3, such clock rates are well beyond the FPGA range. Pity.
You seem to be familiar with PCIe 2 though, so now I'm wondering - is there a chip that could convert the 1x PCIe 3 lane into a 2x or 4x PCIe 2 set of lanes? Also, worst case, if you really wanted to use this chip, couldn't you just use the chip with PCIe 2 (albeit slower, but I think revisions of PCIe are supposed to be cross compatible)?
Never heard of such a thing, although it might have been really useful.

Did not even think of this option, sounds interesting. I guess we should wait for the datasheet for this chip to be sure.
