Samsung 950 Pro NVMe M.2 SSD Review – NVMe for the masses

Synthetic Benchmarks


HD Tune Pro

In this benchmark I am checking sequential reading speed.

NVMe 256GB SSD

With an average sequential reading speed of 2349 MB/s the Samsung
950 Pro M.2 NVMe SSD gives an outstanding turn of speed. Also worth noting are the
incredibly fast access times.

Let’s see how this compares to other recently tested SSDs in
the table below.

The Samsung 950 Pro M.2 NVMe SSD has performed extremely
well in the HD Tune sequential reading test.

ATTO disk benchmark

ATTO has become a standard tool for measuring the data
throughput of HDDs and SSDs. It measures the reading and writing performance,
using different file sizes and block sizes.

The reading speed results for the Samsung 950 Pro M.2 NVMe 256GB
SSD are extremely impressive, topping out at over 2.3 GB/s, and writing speed
is also impressive peaking at over 959 MB/s.

Let’s find out how this compares with other recently tested
SSDs.

ATTO Reading performance

ATTO – Reading
performance at various block sizes

The Samsung 950 Pro M.2 NVMe SSD has outstanding reading
performance with small block sizes, and this is extremely important for a
consumer grade SSD.

ATTO Writing performance

ATTO – Writing
performance at various block sizes

The Samsung 950 Pro M.2 NVMe SSD delivers excellent writing
performance, but it isn’t as fast as the OCZ REVODrive 350 or Intel 750 when
writing larger block sizes.


CrystalDiskMark 3.0

Crystal Disk Mark is quite a handy benchmarking application,
as it focuses on the file sizes that can cause a problem on a system drive.

As we can see from the above screenshots, sequential reading
and writing speeds are both extremely impressive, also random reading and writing
performance, at low and high queue depths, are both outstanding.


AS SSD Benchmark

AS SSD benchmark is a benchmarking tool specifically
designed to test SSDs. The application tests sequential reading and writing
performance, 4K random reading and writing performance.

AS SSD benchmark also tests 4K threaded performance. This is
very exciting, as this test is the first available test that I am aware of,
that simulates how a PC operating system actually works. A modern PC and OS,
such as Windows 7/8 does not just run a single thread at a time, it runs many
threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads
simultaneously throughout the test. If this result is good, then you can be
pretty sure the drive will perform extremely well as a system drive.

After the tests complete, AS SSD benchmark derives a total
score for the drive being tested. This is based on all aspects of the test
results, and gives an indication of how the drive is performing overall.

Now let’s look at the result from the Samsung 950 Pro M.2
NVMe SSD in the form of a screenshot. All our other comparison drives’ results
are presented in the form of a graph.

As we can see from the AS SSD test run, the Samsung 950 Pro
M.2 NVMe SSD has outstanding reading performance. Writing performance is also
impressive, but not quite as fast as the Intel 750. The Samsung 950 Pro M.2
NVMe SSD takes second place in this test.

Summary:

The Samsung 950 Pro M.2 NVMe SSD has performed extremely well
in the basic synthetic benchmarks. Random reading and writing performance is
extremely impressive. Sequential reading performance is outstanding, and
sequential writing performance is also of a very high standard.
