ZOTAC Sonix 480GB NVMe PCIe AIC SSD Review

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







ZOTAC does not specify random 4K performance for the Sonix. With our configuration, we were able to hit maximum 4K IOPS of 340K read and 230K write.



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






Write response is decent, but read response (latency) is higher than we expected to see. This really runs contrary to the outstanding user experience we are getting while running the Sonix as our OS disk.



DiskBench - Directory Copy


Version and / or Patch Used:


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 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 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






The Sonix delivers excellent read transfer performance, as do all the drives in our test pool. The Sonix write transfer performance is the lowest of the NVMe drives we've tested.
