Mines the Asus X99-S.

Yeah I know Freddy 

The -S is just something Asus have added for fun, it is basically an X99 chipset.

The board MUST also have what they are calling:

32Gb/s ultrafast M.2 x4 socket on-board.

That is where you plug this thing in to:

I think your board has it Freddy 

Well I am glad someone remembers what I have 

Yes it has one of those sockets - I had wondered what that was for, now I know.

So you just buy the SSD and plug it in there ? No other sockets involved - so I can keep my spare GPU slots for the future ?

Yes mate, like this:

Ah so that's what that bracket was for.

Super cool. Now I'm interested, but that comes second on my list - I'll wait till the price drops, but that's a nice easy upgrade as I have three SSDs in there now and I don't want a cable-fest going on.

Thanks 

   Intel is still working on using the PCI express lanes for use with it's SSD's, they are working with Asus and finding new ways to get all the potential from their 750 series drives.  Link :

somewhat long video but very interesting.  The webpage also contains links to some other interesting sites.

Some nice info there, thanks Carl2 

Data thought you would like that, they doubled the speed of the sata but they still haven't reached the full potential. The M.2 is offering 32 Gb/s but they are still in the process of making changes, raid will not work and will create a bottle neck, funny ages ago people were using SSD's in raid.  You have to make sure the drive will boot, make sure you have a direct path to the CPU. 
  Since they are still making changes I think I'll sit back and wait and see what they come up with.  I hope it's not to expensive and something relativity simple to do.

If I was to build one today I would go M.2, it offers the best bang for bucks and lower power consumption 

QuotePerformance-wise Intel's SSD 750 400GB and Samsung's SM951 are fairly even. The benchmarks prove that both drives have their strengths. And under normal desktop workloads at low queue depths, I'd go so far as to call them equal..

  I already have the HP as a spare, since it has 6 GB/s  vs the 3 gB/s transfer it is a little quicker.  I'm not in any hurry but I'd be pretty disappointed if the newer system was only a little bit faster.  At present both computers have a quick boot time and are responsive enough.  This compared to the average consumer who is still buying a computer with a standard hard drive. 
  I'm actually hoping Intel will continue releasing 6 and 8 core Cpu's in the latest series although I don't think it will happen, this is the first time I've seen them offered at reasonable prices.
Carl2

Oh it will be faster I'm sure of that, it's about 5 times the speed of the best SATA SSD's

Don't blink.

  I have to admit it was quick, what did I watch?
Carl2

It's apparently Windows 8.1 on a Plextor M.2 SSD, which isn't as fast as the newer Samsung M.2 drive.

Looks like it woke up from sleep,  I watched a few other vids on SSD's, seems the standard SSD using Sata is being replaced by the M.2 or PCI express. 
  I just came across this which looks interesting  " BIOS for native UEFI bootloader "   link

It goes to show that we really don't want to mix older "legacy" hardware with new builds.
This got me thinking - do we really need an internal DVD drive any more ?
I hardly ever use mine, it might be better to get an external USB and just plug it in when needed.
