Trying to raid 2 x Samsung 950 pro PCIe X4 NVME M.2 ?

Don't bother, the Maximus Viii hero does not support it, as Squaker mentioned in his "Disappointing Hero thread"

Like Squaker I am also very disappointed, I have wasted days thinking it was me mis-configuring something. I saw the Asus ROG guide on how to do it, and must admit it was my fault for assuming an almost £200 board from the same range would have this feature. In short I RMA'd my M8H this morning and have purchased the identically featured identically priced Gigabyte GA-Z170X-Gaming 7 motherboard.
I say identically featured but I missed the fact that the Gigabyte board has two independent PCIe 4X M.2 sockets, AND supports raiding them at full speed.

Also, no need to buy the Hyper M.2 X4 Mini adapter, making the Gigabyte £30 cheaper.

Amazingly the much cheaper Asus Z170 A also supports this, it does not make sense.

For me I have gone full circle, I was a massive Gigabyte fan back in the day, I switched to Asus for the P5B deluxe many years ago as they were offering a bit more for the money. Oh how the tables have turned.

there are trade offs on different boards with different features and if you read the reviews of 950's in raid arrays, there is very little gains to be had and in some scenarios negatives
good luck with your Gigabyte

I have looked at the reviews, when raiding 2 of these you get 3GB's per second over the 2 GB's per second when there is only 1, I am aware some boards like the top gigabyte and ASrock let you raid 3 M2 PCIe cards and there is very little if any real world gain to doing that. but 2 in raid is definitely better than 1on its own

point taken, enjoy your setup

Wow wow wow

It's amazing, better than I could have hoped for. For example it is 12 seconds from when I hit the power button to when I can use windows. 9 seconds of that is the bios counting q codes and preparing to come alive, meaning I can boot windows 8.1 pro in 3 SECONDS.

Truly amazing

on a side note I noticed that the Gigabyte spends a lot less time doing post than the Asus.

I have never done a YouTube video before, but I did for this because I am so impressed.
