Iometer - Disk Response
Version and / or Patch Used: 1.1.0
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 five second ramp-up before each test. The drive/array is partitioned and attached as a secondary device for this testing.
Average Disk Response
Write response times benefit most from RAID 0 because of write caching. There is a slight latency increase in read response times for an array vs. a single drive. Read response is the best we've seen to date from a SATA based array. Write response is also excellent; although, our 730 Pro array and our Extreme Pro array are slightly lower.
DiskBench - Directory Copy
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) of mostly incompressible random data as it's transferred from our DC P3700 PCIe NVME SSD to our test drive/array. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive/array's read transfer rate. The system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.
Write Transfer Rate
Read Transfer Rate
Our 850 pro array is able to deliver yet another lab record with read transfers. Write transfer speed is also impressive, with our 850 Pro array nipping at the heels of our Extreme Pro array.
