My 850 is faster than my 950?

One on the board and the other as an add on card.
CPU is 5930k and i'm currently running SLI in slots 1 & 3. Both at x16.
Pics now working. The speed for the M.2 drive is as fast as that drive will go.
I assume your Samsung 850 are in RAID? It's the only way you would achieve that figure.
I appreciate that it says link speed is 10GB/PS which doesnt sound right, however everything else looks fine. Even if you were getting 32GB/PS nothing would change in terms of the read writes as you're at the limit of what the 950 can do.
It's an unfair comparison as you're comparing 2 or more 850's in RAID 0 which will always be faster than a single drive. If you were able to RAID 0 the 2x M.2 slot, it would be faster again than your 850's. In short, nothing is wrong.

Do you have rapid mode enabled for the 850?
If so, it's not a true measure of the 850 speed as it uses dram for cache

Yeah he's got RAPID mode on for the 850. The numbers are meaningless.
The 950s can get a bit toasty and start thermally throttling when benchmarking.
There's a test of with and without heatsink here: http://www.anandtech.com/show/9856/angelbird-wings-px1-m2-adapter-review-do-ssds-need-heatsinks
It doesn't show any justification for adding a heatsink until you get to about page 6 with the 512 benefiting more than the 256.
This may not be the problem you have at all but it's worth testing the temperature of the drive. I think HWInfo will do it if it's not in a RAID array.

I thought that temps were only a problem under serious sustained use which normal desktop usage never really produces.
