Anyone got any experience with these? The performance looks insane on paper.

Title: M.2 ssd

You need to be a little careful here, there are different types of m2 ssd, so you need to match the ssd to compatible hardware.  Some m2 are a lot slower than you quoted.

I have a laptop which boots from one of the first gen m2's and it works well.

Sorry I wasn't so clear with the title (now changed). I meant the NAND/V-NAND Tech. Kingston/HyperX have used the same tech but only got half the read speed, although they do offer a M.2 adapter.

No hands-on experience. I have been eyeing up either the Intel 750's or Samsung 950/951's for my next build.
Not seen many articles discussing NVME drives other than Intel and Samsung.

I like the look of the Intel ones, but I also like idea of the samsung ones just sitting on the Mobo pretty much invisible. A couple of articles mentioned the samsung ones running hot at times, not sure how much that would impact performance.

I love the idea of the main hard drive being a tiny card bolted to the back of the motherboard, but as TL warned there do seem to be a huge array of different (physical) sizes, connections and specifications. When I do do an ITX build I reckon I'll go for one :D

I have a SM951 and when installed in my motherboard's M.2 slot I was getting roughly 700MB transfer speeds, which was rather disappointing and only marginally faster than the 850 EVO I already had.

So I installed it on the Kingston PCIE Adaptor and now get approx 2001MB transfer speeds!

As you say: insane!  My PC now boots up in around 3 seconds. :)
