OakGate Platform – ‘Fresh out of Box’ Tests
These tests provide a highly consistent basis for comparing
solutions. The sequence of tests begins with a purge of the drive to ensure
that it starts in a FOB state.
The tests cover all of the essential IO performance
characteristics.
Sequential Writes
This test performs 20 seconds of Sequential Write IOs for
each combination of Queue Depths 1, 4, and 32, and IO Sizes of 4K, 128K, and
1024K. IO traffic is limited to an IO Range of 1GB (which is equivalent to a
test file size of 1GB).
Here are the results for the Corsair MP300 –

Here is a comparison of the 128K, Queue Depth 32, Sequential
Write performance with the other products I have tested to date –
A good result but again we have not hit Corsair’s
specification of 920 MB/s.
Please note that NVMe drives are tested with an IO Size of
128K.
Let’s also have a look at how the Sequential Writes Power
Consumption compares, but to do this fairly we must divide the average MB/s by
the average Milliwatts to get a value for the effective work done. Here is the
result –
You can see that the Corsair MP300 has an outstanding level
of power efficiency.
Sequential Reads
The test performs 20 seconds of Sequential Read IOs for each
combination of Queue Depths 1, 4, and 32, and IO Sizes of 4K, 128K, and 1024K.
IO traffic is limited to an IO Range of 1GB.
Here are the results for the Corsair MP300 –

Here is a comparison of the Sequential Read performance with
the other products I have tested to date –
This is an excellent, which exceeds Corsair’s specification
of 1580 MB/s.
Random Writes
The test performs 20 seconds of Random Write IOs for each
combination of Queue Depths 1, 4, 32 and 128 and IO Sizes of 4K, 16K, and 32K.
IO traffic is limited to an IO Range of 1GB.
Here are the results for the Corsair MP300 –

Here is a comparison of the 4K, Queue Depth 1, Random Write
performance with the other products I have tested to date –
This is a good result in comparison to the SATA drives but
it falls behind the other NVMe drives.
Let’s have a look at the Latency Distribution for the 4K, QD
1 performance –
This graph shows the Latency for every IO that was performed
in the 20 seconds of traffic. It shows the Number of IOs (IO Count) that fell
within a particular period of Time (Microseconds). The red line plots the Time
against the Percentage of total IOs performed.
You can see that the Corsair MP300 achieves a high level of
consistency and 99.9% of all IOs have a Latency of 30 Microseconds or less
(which can be compared to 20 Microseconds achieved by the Samsung 970 EVO in
this test).
Random Reads
The test performs 20 seconds of Random Read IOs for each
combination of Queue Depths 1, 4, and 32, and IO Sizes of 4K, 16K, and 32K. IO
traffic is limited to an IO Range of 1GB.
Here are the results for the Corsair MP300 –

Here is a comparison of the 4K, Queue Depth 1, Random Read
performance with the other products I have tested to date –
This is a good result but it actually falls behind a few of
the SATA drives I have tested.
4K Random Mixed Reads/Writes
The test performs 20 seconds of 4K Random Mixed Reads/Writes
for each combination of Queue Depths 1, 4, and 32, and Read/Write ratios of
0/100, 30/70, 50/50, 70/30, and 100/0. IO traffic is limited to an IO Range of
1GB.
Here are the results for the Corsair MP300 –

Here is a comparison of the 4K Mixed Random 50% Read/50%
Write, Queue Depth 1 performance, with the other products I have tested to date
–
An excellent result.
Now let’s head to the next page, to look at the results
for the Oakgate Sustained Write and Recovery Tests…..
