Samsung SSD 950 PRO 512GB M.2 NVMe PCIe SSD Review


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 M.2 PCIe SSD 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.

We ran the quick test and it showed the Samsung SSD 950 Pro 512GB SSD had sequential read/write performance of 2601/1542MB/s and a Random Read/Write of 173,328/104,562 IOPS. The sequential performance numbers are close to the drives rated speeds, but the Random read operations was half of the 300,000 IOPS that the drive is rated for.
