Samsung SSD 950 PRO Conclusion
IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes occurring after publication which might render our rating obsolete. Please do not base any purchase solely on this conclusion, as it represents our rating specifically for the item tested which may differ from future versions. Benchmark Reviews begins our conclusion with a short summary for each of the areas that we rate.
Our first rating is performance, which compares how effective the Samsung SSD 950 PRO performs in benchmark operations against storage solutions. For reference, Samsung specifications suggest 2500 MB/s maximum reads and 1500 MB/s write speeds for this model. In our storage benchmark testing with 950 PRO, this M.2 solid state drive performed beyond the advertised maximum speeds and produced results 400% faster than the best SATA SSD’s previously tested. ATTO Disk Benchmark tests proved the 512GB Samsung SSD 950 PRO was good for delivering 2591 MB/s read speeds, and 1595 MB/s write speeds. CrystalDiskMark reported 2600 MB/s average sequential read speeds and 1547 MB/s writes using 32-queries working on 1-thread. Linear sequential testing with AIDA64 Disk Benchmark produced 2310 MB/s average read bandwidth, while continuous sequential writes averaged 1349 MB/s. AS-SSD Benchmark produced 1953 MB/s sequential reads, and 1444 MBps writes.
The 512GB Samsung SSD 950 PRO solid state drive features their 3-core UBX controller advertised to deliver up to 300,000 random 4KB read IOPS and 110,000 write IOPS. Using Iometer operational performance tests configured to a queue depth of 32 outstanding I/O’s per each of four targets, our benchmarks produced 258,752 read IOPS and 94,110 write IOPS. These results give credibility to Samsung’s specifications for SSD 950 PRO. Obviously the PCIe bus plays a critical role in delivering impressive transfer speeds, but Samsung’s UBX controller last seen in the Enterprise-class SM953 SSD helps establish 950 PRO as a truly dominant consumer product.
As to the question of whether Intel’s Z170 Skylake platform is a better choice over X99 Haswell computers, there are some subtle indicators to discuss. Z170 tests didn’t always generate the highest benchmark results, but typically performed to the same level as X99. The difference was so small, it would not be perceivable to even the most sensitive power user. Beyond the synthetic scores, we did see improved consistency from our Z170 tests. Taken together with the benefits of Intel’s Skylake architecture, Z170 is our favored choice of desktop platform.
950 PRO isn’t much to look at. Solid State Drives are typically low-visibility products; seen just long enough to install before they’re forgotten. With the introduction of the diminutive M.2 2280 form factor, now these highly-functional SSDs will become even less visible (and likely less fashionable). To Samsung’s credit, they’ve given the 950 PRO enough color to stand apart from the rest of the motherboard, but just barely. The only remaining visually appealing change they could possibly make is the addition of colorful anodized aluminum heat spreaders.
While construction is typically the strongest feature credited to the entire solid state product segment, M.2 SSDs don’t feature the same protective housing their SATA counterparts enjoy. Apart from the exposed components, Samsung does emphasizes quality with a generous product warranty. If there are ever any problems with Samsung SSD 950 PRO during the 5-year warranty period, end-users may visit Samsung Support or create a Service Request. As with other Samsung products such as 850 PRO, this warranty might later be increased to 10-years as yields improve.
As of October 2015, the Samsung SSD 950 PRO series launches in the following capacities and retail prices:
|950 Pro M.2 NVMe||256GB||MZ-V5P256BW||$199.99|
The new Samsung SSD 950 PRO starts what will become a large movement towards the M.2 form factor, and will be the first of many more to support the soon-to-be standard NVMe protocol. More and more performance enthusiasts will undoubtedly leave SATA to move their primary storage to the PCIe bus, taking advantage of four times the bandwidth along with faster and more productive SSD controllers. The SSD 950 PRO is another pleasant surprise from Samsung, as they once again offer substantial improvements over previous offerings.
In conclusion, Samsung SSD 950 PRO delivers unparalleled performance for its price and ushers in a new generation of solid state drive products sure to become standard equipment on high-end computer systems and portable devices. While 950 PRO may not offer the industry’s least expensive price per gigabyte compared to other solid state storage devices, it’s still very much a value-driven product with very competitive pricing. Considering that no other SSD in this market segment can deliver sustained transfer speeds or operational performance anywhere near the same level, it’s nice to see prices are reasonable. Benchmark Reviews recognizes how well the Samsung SSD 950 PRO delivers top-end performance at a fair price, thus earning our Golden Tachometer Award.
