Intel SSD 750 Series 1.2TB PCIe NVMe Review

IOMeter is another open source synthetic benchmarking tool which is able to simulate the various loads placed on hard drive and solid state drive technology.

Using a queue depth of 32 (in order to test Intel's claims), the 1.2TB SSD 750 delivers just over 460,000 IOPS for the 4K random read test and more than 310,000 IOPS for 4K random write. These are slightly higher than Intel's reported numbers, which may be due to BIOS/driver updates. Random performance is a strength for the SSD 750 and its PCIe, NVMe controller.

Average I/O response time was in the fractions of milliseconds range for the read and write tasks. A high CPU utilisation was required to ensure that enough data was fed to the SSD for its full potential to be reached.

Additional testing with a queue depth of 1 saw the SSD 750 hitting 193,000 4K random read IOPS and 143,000 4K random write IOPS. Those numbers put it well above a typical SATA 6Gbps SSD and even OCZ's and G.Skill's four-drive RAID 0 solutions for random reads. However, the multi-drive RAID 0 solutions were able to register 4K random write IOPS greater than Intel's SSD 750 (~167,000 for OCZ, ~181,000 for G.Skill).
