Iometer – Maximum IOPS

Version and / or Patch Used: Iometer 2014

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

Good results from the TR200. We still can't hit 87K write IOPS though.

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.

Better than average read response. In fact, the 480GB TR200 delivers the best (lowest) read response of all of the drives in our test pool. Write response is another matter. No DRAM cache makes write response sluggish.

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.

Transfer Rate

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 TR200 240GB just squeaks by our minimum thanks in large part to its 3D flash array offsetting its lack of a DRAM cache. As this shows, if you are transferring large chunks of data frequently, then the TR200 is probably not the drive for you. The good news is the vast majority of users aren't transferring huge chunks of data.
