OCZ RD400A Test Setup


In testing the Toshiba OCZ RD400 512GB PCIe NVMe M.2 SSD, I am using a Gigabyte Z170X Gaming 7 motherboard powered with an Intel Core i7-6700K. The CPU is set to run at its default stock speed. Below are the rest of the system specifications:

Operating System: Windows 10 Pro 64bit
Motherboard: Gigabyte Z170X Gaming 7
Processor: Intel Core i7-6700K
CPU Cooler: NZXT Kraken X61
Memory: Klevv Cras DDR4-3000 16GB
Graphics card: Zotac GeForce GTX 1070 AMP! Extreme
OS Drive: Zotac Sonix 480GB NVMe PCIe SSD
Power Supply: Seasonic 1050W Platinum
Chassis: DimasTech Bench Table Easy V3.0

Note: The benchmark results on the succeeding pages are results I got during my tests using the specific sample Toshiba sent. Performance may vary from one capacity to another and from one system to another. You may or may not get the same exact results shown in this review. During my tests, each result does not remain at a constant or fix read/write speeds. The results below are not cherry picked as well. But the results are the more constant numbers I got while running the same benchmark several times.


Aside from testing the OCZ RD400 with its PCIe add-in adapter, I also tested the drive by directly installing it on the M.2 slot of the motherboard. On the benchmark results, we’ll find out whether there’s a difference between using the PCIe adapter and installing it directly on the M.2 slot of a motherboard.
