Toshiba Q300 PRO 1024GB SSD Review

OakGate Platform – ‘Fresh out of Box’ Benchmarks

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).

Sequential Write performance with the other products I have tested to date –

This is an excellent result which exceeds Toshiba’s
specification of 520 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 Toshiba Q300 PRO has a competitive level
of power efficiency, but is falling behind Samsung’s latest SATA products.

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 for an SATA drive and just like
the WD Blue 3D and the Samsungs 860 products, the Toshiba Q300 PRO is pushing towards
the limit of the SATA Bus bandwidth exceeding Toshiba’s specification of 550
MB/s.

Random Writes

The test performs 20 seconds of Random Write 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 Samsung 860 PRO –

This is a good result for an SATA drive.

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 Toshiba Q300 achieves a high level of
consistency and that 99.9% of all IOs have a Latency of 50 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.

performance with the other products I have tested to date –

This is a reasonable result for an SATA drive although it is
significantly behind the remarkable results achieved by Samsung’s recent SATA
products.

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.

This is a reasonable result for an SATA drive but is falling
behind more recently launched competitors.
