If it is installed anywhere other than C: ... then just uninstall (or delete it) and re-install on your primary partition. That should sort your problem. Think it's some sort of write permission issue. A couple of the O/L review sites have fallen foul of this as well. AS SSD did exactly this for me a while back. As without thinking, I unpacked it into the download folder (held on a different drive) and had exactly the same problem. Put it on C: and issue went away.

Im a bit of a newb when it comes to m2 drives.

So how do they work? atm I have 2 regular ssd sata input.

I dont think my mb can use m2 drives. So do I need a mb that can use these? And do they work just the same as regular ssd drives easy to install and set up windows etc?

oh if a new mb is requred what would be the best skylakes compatible mb for one of these?

i am not an expert, but you need a slot on your mobo, its not really new new tech, so you may well have a slot, but to make use of the speeds you may well need a newish mobo. they slot or screw in like a stick of ram and are picked up in the bios and during a windows 10 install, with windows 7 you would prob need the driver on a usb stick to detect.
 
You need either a motherboard with an M.2. slot, or a PCI-E adapter card. M.2. slots first started appearing on high-end Z87 boards. By Z97, most boards have one. If you're on Z68 with a 2700K, I wouldn't bother doing a complete rebuild just to get M.2.

TBH, the difference in real-life performance between an M.2. drive and a SATA SSD isn't great. I've got a PC with an M.2. boot SSD and I really don't notice the difference between that and my other PCs using SATA SSDs. I think in some applications it is faster, but for day-to-day use I'll be sticking with SATA.

EDIT: Win 8.1 and 10 have native support for booting from NVMe providing your motherboard is compatible. Win 7 and 8 (not 8.1) can be a real pain. It's one reason I switched to Win 8.1 from 7 when I upgraded. I'm now on Win 10.

Thanks for the info guys ... and nice to know about the speed differences. So a good upgrade just not something to consider when changing out mbs/cpus.

Id like to wait to see what zen can do before deciding on upgrade both for mb/cpu.
 
When you do eventually change CPU/MB, check what speed the M.2. slot of any new board runs at. My board only runs at 10GB/s, whereas some boards run at the full 32GB/s. It is worth upgrading to M.2. as it means you have 1 less drive to screw/fix inside the case.

I would think that any new mobo (except maybe m-ITX) will come with M.2. as it's becoming much more available and widespread.
 
Do I need to install the samsung driver or is the windows one fine?

It's nice seeing the benchies from this drive but to be honest I'm not noticing anything significantly faster than when I had my 850 Pro as my windows drive.
 
installing on Gigabyte 990fx-GAMING (AMD)

hello.
I have now also got the sm951 256gb nvme and the board does recognise it.
how do i install windows 10 on this ?
what do i need to do ?

I keep getting
"Ensure that the disk's controller is enabled in the BIOS menu",., I am sure it is!!

please help!
 
How does the SM951 work with Win 7? I'm really thinking about getting one as my OS drive. Is it just to plug it in, start up and install everything?

I'm going to use a MSI Z170A Gaming Pro mobo.
 
Mainly due to the fact I got Win 7 available so no need to buy a new OS (as i havent gotten around to try upgrade to win 10 yet).

Might go with Win10 though, but I havent used it at all so got no idea how good/bad it is compared to Win7 that I do like.
