Samsung 840 – 250GB 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.

Anvil’s Storage Utilities is still in beta at the moment,
but the application is currently solid enough to use in this article, and I have
already verified the results obtained using an SATA analyser.

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% (non compressible data)

 So let’s begin the tests.

In the 0 fill test, the Samsung 840 has performed well
overall, and is in the middle of the pack.

The application test pattern is much more realistic in terms
of the type of data that real users will use, and this time the Samsung 840 is
the sixth fastest SSD.

With test data that can’t be compressed at all, the Samsung
840 has still finished this test in sixth place.


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, 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 840 250GB SSD has performed very well in the
Anvil’s SSD benchmark tests. This really shouldn’t be a surprise, as Anvil’s
SSD benchmark focuses on reading performance, and the Samsung 840, as we have already
discovered is a fast SSD when reading data.

 

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