Toshiba OCZ RD400 M.2 PCIe NVMe SSD Review – 512GB


The SSD Benchmark Test System

Before we look at the numbers, lets take a brief look at the test system that was used. All testing was done on a fresh install of Windows 8.1 Pro 64-bit and benchmarks were completed on the desktop with no other software programs running. This means windows defender, windows update, disk fragmentation and everything else that would interfere with testing was disabled. Windows 8.1 also had the power option set to high performance. We also disabled Turbo mode on the Intel Core i7-5960X to ensure our numbers are spot on and repeatable.

ASUS X99 Sabertooth Motherboard

The Intel X99 platform that we used to test the storage drives was based around the ASUS X99 Sabertooth motherboard with BIOS 1801 that came out on 06/25/2015. We used Intel RST storage drivers, the exact version was The Crucial Ballistix DDR4 32GB 2400MHz memory kit was run at 2666MHz with 15-15-15-28 1T memory timings. The Corsair Neutron XT 240GB SSD was used as the primary drive.

The overall capacity shows up as 476GB on the OCZ RD400 512GB SSD in Windows. Note the idle temperature… Without a fan we were at 47-50C and with a 120mm case fan blowing air across the card we were down to 40-43C at idle. At full load you can hit 80C and throttle the drive with poor airflow, so be sure to have proper cooling over the card!


Let’s have a look at the performance!
