Samsung 850 EVO M.2. and mSATA SSD review

PC Mark 8 – Storage Suite

Here at Myce.com, we only recently introduced PCMark Vantage
into our SSD testing. PCMark Vantage is a good test, but is now somewhat
outdated in the applications that it tests, even to the extent of including a
test trace on how Windows Vista booted. We could of course have opted for the
newer PCMark 7, but I personally had issues with the way it ran the HDD tests.

We have built quite a close relationship with FutureMark
software, the authors of the PCMark PC benchmarking software that we use in our
tests. I decided I would use PCMark Vantage as stopgap measure until the more
up-to-date PCMark 8 benchmarking suite became available. I’m pleased to say
that PCMark 8 is now available, and it gives me great pleasure to introduce you
all to the results obtained by this new ‘real world’ benchmarking suite.

I will describe the basic way that each test is carried out,
above the graph for each test.

Now let’s look at the individual PC Mark 8 HDD suite scores,
in the form of tables and graphs.

The first thing that is very noticeable is that all the
tested SSDs are remarkably close, performance wise, when loading this game.

Again, there isn’t a large difference between any of the
competing SSDs, but once more the Samsung 850 EVO mSATA 500GB SSD is the
fastest, with the M.2. version finishing this test in eighth place.

The Samsung 850 EVO mSATA and M.2. SSDs are the fastest drives
in this test.

With only 0.3 seconds between the fastest and the slowest
SSD in this test, I would doubt anyone could tell the difference.

almost identical.

PC Mark 8 storage suite: Storage bandwidth

Storage bandwidth displays the amount of bandwidth available
from the storage device, when it is faced with requests for simultaneous reads
and writes.

Samsung 850 EVO M.2. and mSATA SSD review

According to PC Mark 8, the Samsung 850 EVO mSATA and M.2.
have 321.93 MB/s and 324.27 MB/s of bandwidth respectively.

PC Mark 8 storage suite: Overall Score

PC Mark 8 sums all the individual times taken to run each
storage benchmark, then comes up with an overall score for each of the tested
SSDs.

Samsung 850 EVO M.2. and mSATA SSD review

As we can see from the above graph, there isn’t a large
difference between any of the tested SSDs, but the Samsung 850 EVO mSATA and
M.2. SSDs take second and third place.

Summary

You may well ask, if the scores are so close between the
tested SSDs, then what is the point of running PC Mark 8 storage benchmark?

Basically, most of these individual tests are very low
demand as far as storage is concerned. More or less all the traces are
lightweight. But hang on a minute, this is how real applications work, and I
and many other reviewers have been saying for years that when we have
lightweight storage traces, it becomes almost impossible to tell SSDs apart
from a performance perspective. We now have a tool that can demonstrate this to
very good effect.

It’s not until we start to push SSDs very hard that the
performance differences between SSDs start to become clearer, and for that we
need much heavier workloads, such as the tests run in the Myce Reality Suite.
PC Mark 8 is still very useful, as I’m quite sure that most of you will use at
least a couple of the applications used in these tests, and now you will be
able to compare one SSD to another.

 

Now let’s round off the performance tests with the Myce
Reality Suite on the next page…..
