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 data sets 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.
Corsair Neutron GTX 240GB (0 fill)
With data that is easy to compress, the Neutron GTX is
showing excellent reading and writing performance, and finishes this test in
second place just behind the Vertex 4.
Corsair Neutron GTX 240GB SSD (application profile)
The application test pattern is much more realistic in terms
of the type of data that real users will use, and in this case the Neutron GTX
is performing extremely well, finishing the test in second place.
Corsair Neutron GTX 240GB SSD (100% incompressible)
With test data that can’t be compressed at all, the Corsair
Neutron GTX 240GB SSD is once again doing extremely well in this test,
finishing in second place, and only just behind the Vertex 4.
Performance with the drive 60% full
What is known about SSDs is the following. The more data
that is stored on the SSD then the amount of free clean NAND is reduced, which
will eventually result in reduced performance, so I feel it is important to at
least present some sort of indication of how an SSD will perform when the drive
is more than half full.
For this test the SSD was filled to approximately 60% of its
Once the drive was filled it was allowed a period of four hours
to allow for garbage collection to take place, then a single run of Anvil’s
Storage Bench was run on the drive using the 100% incompressible option.
Corsair Neutron GTX 240GB SSD – 60% full
With the Corsair Neutron GTX 60%, there is hardly any drop
in speed at all.
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 Corsair Neutron GTX has performed extremely well, and according
to Anvil’s SSD benchmark, is almost neck and neck with the OCZ Vertex 4.
Now let’s head to the next page for some real world tests….
