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
We test NVMe SSDs using eight threads at QD32 (QD256). We do this because we want to see what the drive can generate at its maximum attainable queue depth.
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
And there you have it. This is why the 900P is the world's most responsive SSD. Look at the 900P's read response. It is roughly 6x better than the 960 Pro.
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 a newer version of Windows 10; this is a good reason.
There is enough sequential data in our data block that the 900P doesn't win this test.
