The SSD Benchmark Test System

Before we look at the numbers, let’s 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 ASUSX99 Sabertooth motherboard with BIOS 1702 that came out on 04/15/2015. We used Intel RST storage drivers, the exact version was 13.1.0.1058. 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.

CrystalDiskInfo 6.3.2 Readout:

The readout on CrystalDiskInfo 6.3.2 shows both the Samsung 850 Pro and 850 EVO 2TB SSDs support S.M.A.R.T., NCQ, TRIM and DevSleep. The drives we received were pre-production loaner samples that have firmware version EXM02B6Q for the 850 PRO 2TB and EMT01B6Q on the 850 EVO 2TB. Samsung said that the might change or update the firmware before product ships to retail market sometime in July. The Samsung Magician software supporting the 850 EVO/PRO 2TB drives is not available at this time, but it is expected to be released in the middle of August if all goes as planned.

Samsung 850 Evo 2TB SSD

The overall capacity shows up as 1.86TB on the Samsung SSD 850 Pro and 1.81TB on the Samsung SSD 850 EVO in Windows. The reason the capacity is different on these two drives is that the 850 EVO uses 3D V-NAND 2-bit MLC memory and the 850 Pro uses 3D V-NAND 3-bit TLC memory.
