The arrival of the solid-state drive (SSD) has revolutionised the speed at which modern PCs perform common tasks. This is because SSDs have no moving parts, compared to larger, bulkier mechanical drives, thus they store information on memory chips. This means that accesses, reads and writes are many, many times faster

256GB Samsung PM961 Polaris M.2 NVMe (22x80) PCIe 3.0 (x4) SSD, Polaris, Read 2800MB/s, Write 1100MB/s, 250k/180k IOPS is rated 4.9 out of 5 by 14.
Rated 5 out of 5 by from Blazes through tasks. I have always wanted a M.2 drive and finally, when I did a new build, this was a necessary part of my spec. It is very fast and blazes through tasks. It is a good space for boot, windows files and apps. 256GB is a sweet spot for me. I have a dedicated SSD for my Steam library.

Rated 5 out of 5 by from Blisteringly fast. Went in an Intel Nuc Kit alongside an existing SATA SSD with no problems.

Rated 5 out of 5 by from Superb value for money! I used this as my c: drive for my new AMD Ryzen 5 1600X / Asus Prime X370-PRO AM4 build and was not disappointed. I read alot about installing the Samsung drivers to get the best out of this SSD but in my fresh Windows 10 Pro 64 build it was recognised easily and gave excellent performance out of the box. Installing the Samsung drivers only improved the write performance and reduced the read slightly. But for the money a great buy. My system boots in 10 seconds!

Rated 5 out of 5 by from Ulttra High speed for low £ Purchased this for my new Ryzen Build. * make sure to install the Samsung drivers before you do anything after windows install to get the most from this drive. Super fast gets very high bench marks on my system ([email protected]). Cheaper than their evo series with a very very small performance deficient. Recommended highly

Rated 4 out of 5 by from Not easy to instal I bought this along with a Stryx Z270 mobo and a i7 7700K for a new build, but could not for the life of me get Windows to see the drive when installing the OS. Ended up buying a standard SSD and everything went tickety boo. I imagine if you're installing this with the OS already in place then you won't encounter the issues i had.

Rated 5 out of 5 by from Speedy Hard Disk Ordered this for a new pc I was building, this was to be the system boot drive. I can't criticize this ssd at all. The new pc boots lightening fast; well worth the outlay. Scan delivered the product safely and promptly.
