Iometer – Maximum IOPS

 

Version and / or Patch Used: Iometer 2014

 

We use Iometer to measure high queue depth performance. (No Partition)

 

Max IOPS Read

We could not find any XG3 factory specifications for 4K random performance, so we don't know how our configuration compares. We are able to hit 291K/198K with our configuration. The XG3 delivers double the maximum write IOPS of Samsung's SM951.

 

 

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.

The Samsung drives in our test pool deliver the best (lowest) latency at QD1. The XG3 is able to outperform Zotac's Sonix with both read and write and Intel's 1.2TB 750 Series with read.

 

 

DiskBench – Transfer Rate

 

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 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.

The XG3 delivers excellent read transfer performance, as do all the drives in our test pool. The XG3 outperforms all of the competition with read transfers, delivering nearly 2TB/s!
