Iometer - Maximum IOPS

Version and / or Patch Used: Iometer 2014

We use Iometer to measure high queue depth performance.

Max IOPS Read

Max IOPS Write

We are able to easily exceed Intel's maximum random 4k IOPS specifications of 430K/230K. The 400GB 750 is a real powerhouse.

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.

Take a look at the read response times of the 400GB 750; it is significantly better than the 1.2TB 750, exactly as we saw with our synthetic testing.

DiskBench - Directory Copy

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 random and sequential data as it's transferred from our DC P3700 PCIe 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 drives 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

intel-750-400gb-nvme-pcie-gen3-x4-aic-ssd-review_40

As we would expect, transfer rates are a bit lower with the 400GB 750 than the 1.2TB version.
