Samsung 850 EVO M.2. and mSATA SSD review

 

Anvil’s Storage Utilities

As well as performing SSD endurance tests. Anvil’s Storage
Utilities has a very nice SSD benchmarking application. The SSD benchmark tests
many different aspects of SSD performance, including 4K random at different
queue depths, and also sequential performance, but more importantly than this,
all using real test data.

Another very nice feature of Anvil’s SSD benchmark is the
fact that you can change the compression levels of the test data. The
compression levels of the datasets used for the tests can be varied from 0%
compression right up to 100% compressed data, and there are even a few data
profiles already included, such as database (8%) compression, and also an
application profile (46%) compression, which is designed to simulate real
application data being read and written to the SSD.

I will include a screenshot of the review drive, and all
comparison results will be presented in the form of graphs. If you would like
to see screenshots of the test results obtained on the other SSDs in this
article, you can do so by following the link here.

I will also be testing three different compression profiles,
which are as follows.

  • 0 fill (100% compressible data)
  • Application simulation profile (46% compressed)
  • 100% (incompressible data)

 So let’s begin the tests.

In the 0 fill test, the Samsung 850 EVO mSATA and M.2. SSDs
have performed extremely well, and are the fastest SSDs in this test.

The application test pattern is much more realistic in terms
of the type of data that real users will employ, with the Samsung 850 EVO mSATA
and M.2. SSDs being the fastest SSDs in this test.

With test data that can’t be compressed at all, the Samsung
850 EVO mSATA and M.2. SSDs are still exceptional, and finish the test in first
and third places respectively.

Summary

One should keep in mind that although Anvil’s Storage
Utilities SSD benchmark is a very good benchmark, and tests many aspects of SSD
performance, ultimately it is demonstrating which SSD is technically the
fastest when reading data, and this may not be showing (for example) which
drive will be fastest in the real world with a home user’s work pattern.

The Samsung 850 EVO mSATA and M.2. SSDs have however performed
exceptionally well in Anvil’s SSD benchmark tests, with the M.2. version coming
out on top.

 

Now let’s head to the next page for some real world tests….
