Toshiba OCZ RD400 M.2 NVMe SSD Review

Synthetic Benchmarks


HD Tune Pro

In this benchmark I am checking sequential reading speed at
a file block size of 4MB.

NVMe 512GB SSD

With an average sequential reading speed of 2626.7 MB/s the Toshiba
OCZ RD400 M.2 NVMe SSD gives an outstanding turn of speed. Also worth noting are
the incredibly fast access times.

Let’s see how this compares to other recently tested SSDs in
the table below.

The Toshiba OCZ RD400 M.2 NVMe SSD has performed exceptionally
well in the HD Tune sequential reading test, and finishes the test in first
place.

ATTO disk benchmark

ATTO has become a standard tool for measuring the data
throughput of HDDs and SSDs. It measures the reading and writing performance,
using different file sizes and block sizes.

The reading speed results for the Toshiba OCZ RD400 M.2 NVMe
512GB SSD are extremely impressive, topping out at over 2.7 GB/s, and writing
speed is equally impressive peaking at over 1.65 GB/s.

Let’s find out how this compares with other recently tested
SSDs.

CrystalDiskMark 3.0

Crystal Disk Mark is quite a handy benchmarking application,
as it focuses on the file sizes that can cause a problem on a system drive.

As we can see from the above screenshot, sequential reading and
writing speeds are both extremely impressive, also random reading and writing performance
are outstanding, both at low and high queue depths.


AS SSD Benchmark

AS SSD benchmark is a benchmarking tool specifically
designed to test SSDs. The application tests sequential reading and writing
performance, 4K random reading and writing performance.

AS SSD benchmark also tests 4K threaded performance. This is
very exciting, as this test is the first available test that I am aware of,
that simulates how a PC operating system actually works. A modern PC and OS,
such as Windows 7/8 does not just run a single thread at a time, it runs many
threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads
simultaneously throughout the test. If this result is good, then you can be
pretty sure the drive will perform extremely well as a system drive.

After the tests complete, AS SSD benchmark derives a total
score for the drive being tested. This is based on all aspects of the test
results, and gives an indication of how the drive is performing overall.

Now let’s look at the result from the Toshiba OCZ RD400 M.2
NVMe SSD in the form of a screenshot. All our other comparison drives’ results
are presented in the form of a graph.

As we can see from the AS SSD test run, the Toshiba OCZ
RD400 M.2 NVMe SSD has outstanding reading performance. Writing performance is
also extremely impressive, but not quite as fast as the Intel 750 or the Samsung
950 Pro 512GB. The Toshiba OCZ RD400 M.2 NVMe SSD takes third place in this
test.

Summary:

The Toshiba OCZ RD400 M.2 NVMe SSD has performed extremely well
in the basic synthetic benchmarks. Random reading and writing performance is
extremely impressive. Sequential reading performance is outstanding, and
sequential writing performance is also of an extremely high standard.
