Samsung XP941 M.2 PCIe SSD Review (512GB) – New Ultra Standard Exceeds 140K PCMark Vantage Score

TSSDR PCIE SYSTEM BUILD AND TEST PROTOCOL

SSD Testing at TSSDR differs slightly depending on whether we are looking at consumer or enterprise SSDs.  For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide, although CPU C States have not been changed at all.  Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

New to our bench is a PCIe 3.0 X16 Dual M.2/NGFF adapter, which should take care of any future higher performing M.2 SSD needs. A bit amusing is the fact that this card was configured for our needs and doesn’t quite fit computers as it should, as it needs to accommodate full length M.2 form factors at some point. This adapter can be obtained from Soliton Technologies.

SYSTEM COMPONENTS

This new PCIe Test Bench build was the result of some great relationships and purchase; our appreciation goes to be quiet, Corsair, Crucial, Intel and InWin for their support in our project.  Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

BENCHMARK SOFTWARE

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, QuickBench, Crystal Disk Info, Crystal DiskMark, AS SSD, Anvil Storage Utilities,and PCMark Vantage.  In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and, also, to provide validation to results already obtained.

CRYSTAL DISK INFO VER 5.5.0

Crystal Disk Info provides some excellent information about the SSD itself to include its health, product information, ‘power on’ information as well as the characteristics of the SSD. We can see that the SSD is capable of TRIM as it is not grayed out as with AAM.

ATTO DISK BENCHMARK VER. 2.46

ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Highs of just over 1GB/s read and just under that write speeds are incredible, although we had hoped for a bit higher as it is rumored that the XP941 might be capable of 1.4GB/s.
