Samsung 950 Pro M.2 NVMe 256GB Review
Category : Storage
Published by Marc Büchel on 28.01.16
With the 950 Pro Samsung launches an NVMe-SSD for end users. The drive which is lying front of us in this case performs extremely well pumping out up to 2200 MB/s sequentially reading and 900 MB/s sequentially writing. This definitely makes us wonder how much of that horsepower is available in real life.

Samsung is amongst the first companies which launched an NVMe SSD for end users. NVMe or NVM Express stands for Non-Volatile Memory Host Controller Interface Specification (NVMHCI). These specs define how solid state drives are being accessed through the PCI Express bus and therefore directly communicate with the CPU. NVMe replaces AHCI in the case of SSDs and it brings quite a few advantages to the table. AHCI, or Advanced Host Controller Interface, was optimized for drives with low throughput and high latencies. Apart from that it could not deal with high parallelism, being limited to a queue depth of 32. NVMe on the other hand has been designed to leverage the benefits of SSD from ground up, which means it can deal perfectly with low latency and high throughput drives. Apart from that it supports another magnitude of parallelism, whereas the queue depth can reach up to 65536. Since SSDs are based on controllers, which usually feature between eight and ten channels, parallelism is a key factor in gaining more performance.

Having a closer look at the specs we see that Samsung claims the 256GB 950 Pro M.2 can reach up to 2200/900MB/s sequential read/write speeds, which is simply a new level when it comes to the desktop market. Apparently this kind of performance in combination with a high-capacity drive doesn’t result in a bargain, which is why for instance the 512GB drive will set you back 319 Euro. Nevertheless, for this kind of money you really do get a drive, which outperforms almost anything available on the market to date and also offers a good amount of capacity.
A closer look at this M.2 expansion card shows, Samsung is using their 3 core ARM controller in the UBX version as well as second generation V-NAND memory. Therefore 32 layers of NAND flash memory are being stacked, which allows for 128Gbit of density. Per memory chip this translates into 128GB of capacity. At the moment Samsung is building 256GB as well as 512GB models. At a later stage, when the vendor switches to 48 layer V-NAND a 1 Terabyte drive is going to be available as well.

Conclusion



Announcement: Despite the circumstance that the rating of a product is based on as many objective facts as possible there are factors which can have an influence on a rating after publication. Every autor may perceive data differently over time whereas one possible reason for example is a deeper background knowledge or understanding of certain processes. Certain unforseen market conditions as well as changes have the potential to render a descision made at a certain point in time obsolete.

With their 950 Pro M.2 series Samsung created new SSD, which address enthusiasts and professionals. All new NVMe drives these dasy simply raise the bar in terms of performance to another level and bringt the entire consumer market big step forward. Throughput rates in the region of 2'200 MB/s are about four times as much then what’s achievable with SATA-III, which puts these NVMe drives in a completely different league.

In terms of raw performance our test drive was able to score 924 MB/s sequential write and 1'868 MB/s sequential read throughput. When it comes to 4K IOPS we measured 83'300 IOPS regarding random read and 220'700 regarding random write. The performance of this drive is simply insane, outperforming the SATA-III standard almost by a factor of four regarding sequential read. On another note we also had a look at performance with different queue depths as you can see on page 10. In the case of random read performance at QD1 we see 12'700 IOPS and when it comes to random write we measured 58'000 IOPS. 

Today the 950 Pro M.2 is available with either 256 Gigabyte or 512 Gigabyte capacity. The 256 Gigabyte model costs 191 Euro and the 512 Gigabyte M.2 stick sells at 319 Euro. Those drive are definitely not cheap, but considering what you get the price is adequate. The performance is just mindblowing and the whole NVMe standard helps pushing the boudries of how fast SSDs can be. Should you be an enthusiast or a professional looking for a fast M.2 drive, then we can recommend these drive without a shadow of a doubt.
