Solid-state drives (SSDs) are fast becoming the must-have PC components of 2010. Serving as primary storage space for high-end computers, SSD's super-fast transfer rates and near-instant accesses offer genuine advantages over traditional spindle-based magnetic drives.

A motherboard’s main job is to act as a conduit between the various hardware elements that make up a PC. It needs to be able to link the desired CPU(s), system memory, graphics card, hard drive(s), and add-in cards and enable them to work in harmony.

Rated 4.6 out of 5 by 27 reviewers.
Rated 5 out of 5 by 256GB Samsung SM951 Fast SSD , Working with old Z77 motherboard ,bios chip have to be modified. 13 May 2016
Rated 5 out of 5 by A noticeable improvement on a regular SSD Thought I'd give one of these a go as my new motherboard came with the relevant slot and I'm glad I did. When tested, sequential read/write speeds were around the 1200mbps mark compared to the SSD I took out that had readings of 500mbps. I'm not going to say this has knocked tens of seconds off my boot time as I was already getting a good boot time with Windows 10 64bit on my original SSD but what I am noticing is how much quicker large programs are to launch and settle...that's where I'm seeing the jump. I'm not a PC gamer so I can't comment on the difference for game loading etc. Installation was easy; BIOS saw it straight away and Win10 was happy to install to it. Not overly expensive for the performance difference and a bonus that you can forget all about which SATA port your boot disk was plugged into when moving your board to another case for instance. 28 April 2016
Rated 4 out of 5 by Blisteringly fast, but too cutting edge with several issues. So like a few people I have made the choice to upgrade to skylake as a result of lower prices, but am now regretting that decision for a number of reasons. With regard to this Samsung sm951 m.2 NVMe SSD I had the following issues - 1. It’s not as fast as advertised, on high end board/s and i7 6700k I only saw the following figures via CrystalDiskMark - Sequential Read 1750MB/s, Write 1250MB/s and 4K r/w were 52MB/s and 341MB/s - so still vastly superior to ANY Sata based SSD. 2. Almost all of my SSD tools would not see the NVMe based device, I use Acronis for imaging and PartedMagic for factory resetting before installing windows etc. I eventually got Acronis working by creating a WInPE based USB recovery stick. But no Linux tool I could find would touch the NVMe drive to factory reset it, like I can do with PartedMagic on any Sata based SSD. 3. Samsung Magician doesn’t recognised the drive, which is complete and utter FAIL on Samsung's part, as it can see the sm950pro drive which is essentially the same part, just slower. That and the DOS utility doesn’t see it, on that subject Samsung still need to fix their DOS utility so it displays correctly on PCIe cards. 4. I testing the SM951 in three different Intel Z170 based boards (Asus, MSi & Gigabyte), and in all of them it add 5-10 seconds to the boot time. How can a drive that’s faster than my old Samsung 840 EVO be slower to boot. I am guessing this is yet another total FAIL on the part of Intel's with the Z170 chipset. So in a nutshell, it’s brilliant drive let down by several direct and indirect issues. 15 April 2016
Rated 2 out of 5 by very fast while working failed after a few days scan brilliant cust service though as usual refunded it on day of return 12 April 2016
Rated 5 out of 5 by Unbelievably Good All I can say about this is WOW it is screamingly fast easy to install and great value for money just wish it was 1TB. Once installed I ran some tests and it was topping out on 2.3 GB per sec so either my software is duff or its even faster then specified. Makes a pc boot like a tablet. Truly amazing!! 11 April 2016
Rated 5 out of 5 by Hardware great! Figuring out how to use it is more difficult This comes with no docs. The Asus motherboard has little mention of the slot. So physical installation takes a bit of thinking and surfing. Then getting Windows 10 to boot from it when there are SATA devices also in the system was problematic. Disconnected SATA and installed Windows before reconnecting SATA, not ideal for spreading partitions across devices..... So hardware might be good but BIOS and OS support is a bit immature. Boots really quickly now. 09 April 2016
Rated 5 out of 5 by very happy purchase for asrock motherboard m2 really notice the speed 3mm thick and the size of a thumb ,,,,,,small it pack's a goliath punch in competition 07 April 2016
Rated 4 out of 5 by Very fast and a great price This is one fast drive as long as you have a motherboard that can take full advantage of it. I've fitted it to my Asus Z97-K which doesn't give me the full bandwidth this drive can handle but when so, it's noticeably faster than a SATA drive.

Answer: 
Yes, you can.
I'm using this combination and I'm really happy with it.
Just remember that system needs to be install in UEFI.
Sometimes you will have to make changes in BIOS - you can find on youtube how to do it - but my ProGaming was already set up from new.

I did install Windows 8 and windows 10 on it and both works fine.

Answer: 
Yes you can, though you wont be able to install Windows 7 from a DVD as the Win7 install program does not detect the SSD (Don't know if this is because it is NVMe or M2 Ultra). (I believe you can installed Win7 from a Bootable USB Pen though).

If installing Win8/8.1/10 you should have no issues.

Please also note that if you are running 2x GPUs on this motherboard you will not be able to use this device as a Ultra drive as you will have no available PCIe Lanes (4th Gen I7 have 16 Lanes - 8GPU - 8GPU leaves 0 for M2 Ultra) If you ever are going to install as 2nd GPU then you need to upgrade to X99 / 5820K.

Hope the above helps.

Answer: 
I used it on the Z170A motherboard no problem with a fresh install of windows 10 as the boot drive, just a switch in the onboard devices page in your bios for M.2/sata express with the board installed before windows installation.

The compatibility list on the Gigabyte website is a bit old, and technically I believe it has a four lane M.2, and in later bios can cope with NVMe, so I was hoping...

Answers

Answer: 
In short, yes it works, with a bit of extra effort!

I contacted Gigabyte about this issue, they said that they have tested the model up and the model down from this drive, so they "don't see any reason why this wouldn't work". I thought that was justification enough to give it a shot, and have set up a computer with this drive in a Gigabyte Z97-D3H, and it works great.

Note that I had some issues getting the motherboard to "see" this drive straight out of the box. The BIOS that comes preloaded on the motherboard is only "Rev 5", whereas the BIOS available on Gigabytes website is "Rev 7". After flashing the BIOS, I disabled the SATA III port in which a 3TB non-SSD was installed, to "force" Windows 10 to install on the SSD. Once it was installed I re-enabled the SATA-harddisk and everything worked great - windows boots in <10 seconds.
