Samsung 960 Pro 2TB M.2 NVMe PCIe SSD Review (Page 7)

Iometer – Maximum IOPS

Version and / or Patch Used: Iometer 2014

We use Iometer to measure high queue depth performance. (No Partition)

Max IOPS Read

Max IOPS Write

When we tested the SM961, we were blown away by the maximum IOPS that the drive was able to generate. The tiny SM961 was able to best Intel's massive 750 Series 1.2TB AIC. The Intel 750 Series had ruled this test for more than a year.

The 960 Pro delivers similar maximum read IOPS to that of the SM961, but take a look at the maximum random write IOPS that the 960 Pro can generate. 371K random write IOPS is yet another lab record for a consumer SSD.

Iometer – Disk Response

Version and / or Patch Used: Iometer 2014

We use Iometer to measure disk response times. Disk response times are measured at an industry accepted standard of 4K QD1 for both write and read. Each test runs twice for 30 seconds consecutively, with a 5-second ramp-up before each test. We partition the drive/array as a secondary device for this testing.

Chalk up another lab record for the 960 Pro. The 960 Pro delivers the best (lowest) read response of any consumer/client SSD we've tested to date. As expected, Intel's 750 Series 1.2TB SSD remains the lab champion for write response.

DiskBench – Transfer Rate

Version and / or Patch Used: 2.6.2.0

We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) composed primarily of incompressible sequential and random data as it's transferred from our Toshiba RD400 1TB NVME SSD to our test drive. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive's read transfer rate. Our system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.

We recently upgraded our test system to Windows 10 build 14393. With that upgrade, write transfer rates almost doubled. The reason for this, as far as we know, is that CPU power switching modes have been relaxed on the latest version of Windows 10. We included the NVMe drives we've tested to date on this build of Windows 10. If you needed a good reason to upgrade to Windows 10 build 14393, this is a good reason.

The 960 Pro sets another lab record, this time for write transfer rates. The write transfer performance of Intel's 600P is laughable. It is hard to imagine that the 600P is an NVMe SSD considering there are mechanical hard drives that can transfer data faster.
