Adata XPG SX8200 480GB NVMe SSD Review

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 SX8200 –

Here is a comparison of the 1024K, Queue Depth 32,
Sequential Write performance with the other products I have tested to date –

Please note that NVMe drives are tested with an IO Size of
128K.

This is an excellent result which exceeds Adata’s
specification of 1,700 MB/s.

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 SX8200 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.

This is an excellent result which exceeds Adata’s
specification of 3,200 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.

This is an excellent result.

Let’s have a look at the Latency Distribution for the 4K, QD
1 performance –

Adata XPG SX8200 480GB NVMe SSD Review

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 SX8200 achieves a high level of consistency
and that 99% of all IOs have a Latency of 20 Microseconds or less.

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.

This is an outstanding result.

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.
