Chicken-and-egg problem.
Modern UEFI boards support NVMe and new OS's support it. But part of the problem is that the change is not going to impact most people so it's a low priority. It's starting to make headway in the enterprise market, though.
I had my eye on the SM951 NVMe but was put off by there not being a proper driver for it and it not working with Samsung Magician.
Win 10 round the corner and want it to go on one. Will somebody please take my money! :/
As advanced prototypes were shown at Computex'15 at the beginning of July I would be asking this question if nothing comes out during H2. Somebody who makes 1TB M.2 NVME close to the max speed of PCIE 3.0x4 will get my plenty of cash . Though 1TB might be beyond the present reach.

mSATA hits 1TB, so don't see why M.2 should be too far behind (form-factor / space wise)
M.2 can actually be way larger. The standard allows huge sizes
How? (ELI5)
The delay is possibly due to m.2 only allowing the use of two PCI-E lanes until u.2 connections (which allow using 4 PCI-E lanes) become available.
I'm not sure why Intel is not supporting the M.2 form factor on their 750 nvme drives - i.e. their consumer P3500s (other than the supposed 512GB limit for the m.2 form factor, which would limit them to only one model sold), so I guess the Samsung SM951 will be the first m.2 nvme drive.
I'm probably going to give up and just get a PCIe 750 drive for my desktop, it sounds like it will be generally more compatible than the samsung drive anyways. Doesn't help those with laptops, I know. I would probably get the AHCI version for a laptop for now, since the NVMe version runs even hotter than the AHCI version, and that one will already hit thermal throttling in most non-desktop replacement form factors.

The Intel 750 comes in u.2 form, and there are u.2 to m.2 adapters made by MSI, ASRock and others.
many exist already with 4x lanes

this is band for your buck board brand. Plus many brands have had this out for a long time.
lol
I shouldn't have posted in such a sleep deprived state; I totally thought you were talking about capacity, not physical size.
huh?
My reaction precisely. I must've quoted the wrong post.
i am lost now :/
that toshiba drive has potential
I don't want to upgrade from 256GB until I can get 1TB for a decent price.
Why upsize your boot drive at all? Go for a fast/small/cheaper M.2/PCI-E drive for your boot drive where it'll make the most difference, if you think you'll benefit from it (Adobe apps with scratch space, etc)...
And/or otherwise just start swapping HDDs for SATA SSD for data, those 1TB 850 EVO are cheap enough IMO.
I'm gonna start my Skylake build with a 256GB SM951 + a 1TB 850 EVO, will probably add a second one in RAID before the year's over (or JBOD, remains to be seen, single fast data volume is more convenient tho).

The controller is the same 18-channel behemoth running at 400MHz that is found inside the SSD DC P3700. Nearly all client-grade controllers today are 8-channel designs, so with over twice the number of channels Intel has a clear NAND bandwidth advantage over the more client-oriented designs. That said, the controller is also much more power hungry and the 1.2TB SSD 750 consumes over 20W under load, so you won't be seeing an M.2 variant with this controller.
There are some large NVMe 2.5" enterprise SSDs coming and a few for consumers:
Seagate Nytro XF1440, XM1440, XP6500 (4TB)
OCZ NVMe Z-Drive 6000 Series (6.4TB)
Toshiba XG3, PX04P
This is what Anandtech had to say about the M.2 form factor and Intel 750 1.2TB,
In the links above, it appears that M.2 will soon be differentiated primarily into laptop use or smaller capacity drives connected to an NVMe adapter, while nVME/PCIe slots will be for the larger drives. Out of all of those drives, only the Toshiba PX04P series mentions using a (SFF-8639) U.2 connector or optional NVMe adapter. The U.2 connector allows you mount newer SSDs with a flexible cable instead of a PCIe slot, but like the M.2 is limited to PCIe 3.0 x4. While the Nytro XP6500 claims to use a PCIe 3.0 x8 interface instead of x4. It will be interesting to see where the future is headed because it appears that manufacturers are already pushing these specs. I'm guessing that NVMe adapters are going to be the highest-end SSDs until they make a newer U.2 connector & cable.
some of us have 300GB of programs. Adobe CS 6.0 is freaking huge. Then you have windows, games, AutoCAD (), office, other programs, and so on. I have 100+ programs plus I also like to keep certain high usage data on my actual fast drive. Photos are much faster to view, edit, and stuff on an SSD. Gawd does Bridge suck on a HDD. I even load my photos into RAM to just cut out the SSD all together. Well did. I currently don't have enough RAM to do that ATM.
I have a 480GB drive and I want NVMe but I don't want a side upgrade in terms of capacity. I want an upgrade in speed and capacity. You also have to realize some people i.e people like me have to over provision 25% because that stupid endurance wall is a bitch. I do 120GB writes a day and 350GB reads a day (average so some days i bet are liek a TB). Don't ask me how but I do. Larger the drive the longer the time is until that endurance wall is hit. I will literally have my PC hang because of the SSD. Never happened with a HDD though :/ SSDs are fast until you hit that endurance wall and then they can be slower than a HDD
@wirk I hope it is actually competitive in price and performance. Too often it ends up just being 2 real options in terms of NAND. Extreme Pro or 850 Pro rest suck. 750 or SM951 depending on what your doing.
Samsung crop of SSDs, among others M.2 NVME PM953, a follower of SM951 with up to 960 GB. Big capacities too.
Games aren't gonna benefit much, if at all, from being on a bleeding edge drive. How much does that 300GB shrink to once you take them out of the equation? There's no reason you can only have a single SSD...
Even a 512GB SM951 or 400GB 750 is relatively affordable, data and games can be on a cheaper SATA SSD. Once you actually start working on photos they either reside on RAM or the scratch file on your faster drive.
For exporting/importing larger/cheaper SATA SSD are fine... I'd be really curious what kinda workload actually produces that much in writes a day, are you just hibernating to the drive several times a day?
It went up or down. It is noted in other posts. I went from 90 to 100 then to 110 or 120 so it is either slightly lower or higher on average, which is scary because that's life span average. So for me to change from 90-116GB per day when I was at 50% that many writes is scary.
I seem to remember from one of your previous posts that a lot of it was moving stuff around because your SSD is too small, though I could be wrong. I wonder if your workflow would change with a 2TB SSD. The Samsung 850 Pro 2TB is $1000.
It's probably pointless to ask, he alluded to other threads but from what I've seen the story's always the same "I don't know! I do stuff! It happens!"... Wouldn't wanna cause him any more mental stress if he happens to delete another post by mistake (i kid guy, I've been there).
It'd probably benefit him to figure it out but it doesn't seem to be in the cards, no offense meant btw, not everyone has the time to trouble shoot and optimize stuff. Sometimes throwing money at a problem IS cheaper in the end.
We don't know how your workload pans out that way either, and you keep bringing it up, which is why many have tried to question what's going on... It's not a personal attack, and I don't think they're doubting you either (I'm not anyway).
I dabble in photography a lot too and often dump RAWs on the main SSD when I know I'll be working them over a while, even tho it's one more step in the processing workflow... Still not seeing that amount of writes but maybe you do it that much more frequently (I certainly don't re-install the OS twice a year, what is this 1998?)
In wanting to get away from that (and from swapping games in and out too) is why I'm going to a faster but small/affordable drive for the OS/apps *that really benefit from it* then cheaper/larger SATA SSD for the rest, hence my suggestion earlier.
You don't need one SSD to rule them all inside the system when you can get a cheap 850 EVO and pair it with something faster for the things that'll really benefit from it (and no, storing RAWs isn't that demanding IMO).
Sounds like you've already got a plan tho so good luck with it! Build log or it didn't happen btw.
