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

We are getting 17K more random read IOPS than the factory spec of 75K IOPS at QD32. We are close enough to hitting Intel's factory spec of 85K to call it 85K.

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.

This testing bypasses the drives SLC cache, which is why the read response isn't better. It is still very good especially when we compare it with the SU8000 which has a somewhat similar hardware configuration.

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 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.

When testing write transfer rates, we have a rule of thumb. If any SSD cannot achieve 200MB/s with our write transfer test, that SSD will not receive a TweakTown recommendation. There are many TLC SSDs that do not pass our minimum, but we didn't include those on our chart. Additionally, we recently updated to Windows 10 Anniversary Edition and with that update, sustained write performance greatly increased. This means our previous transfer tests cannot be compared with those run on the newer version on Windows 10. This is the reason we only have a few drives on our chart.

The SSD 5 545s passes with flying colors. We believe the SU800 and MX300 have better write transfer rates due to the built-in OP that is inherent to 384Gbit flash. The 545s displays a nice balance in read/write transfer rates.
