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
Samsung arrives at their maximum random IOPS figures by testing with four threads at QD32 or QD128. We test with eight threads at QD32 or QD256. We do this because we want to see what the drive can generate at the maximum viable queue depth. The 960 EVO's are both capable of pushing out over 600K read IOPS at QD256. This is even better than our previous consumer champion, the 960 Pro 2TB.
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.
Avg. Write Response
Avg. Read Response
The 960 EVO's don't win out for either read or write response. They do deliver better (lower) write response than the 950 Pro, but the 950 Pro delivers superior read response. When we compare the write response of the 250GB 960 EVO to the 1TB model, we again see that the DRAM ratio on the 250GB model gives it the advantage. Intel's 750 delivers the best write response, the 960 Pro the best read response.
DiskBench - Transfer Rate
Version and / or Patch Used: 220.127.116.11
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.
Write Transfer Rate
Read Transfer Rate
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 data block we transfer exceeds the 250GB 960 EVO's TurboWrite layer, resulting in a significantly lower write transfer rate than we get from the 1TB model.
