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

Crucial specs the BX300 240GB for 95K random write IOPS. Maybe with Windows 7 that's possible, but definitely not with Windows 10. On the other hand, we are exceeding factory max random read specs by over 15K.

 

 

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 BX300 delivers about average response times.

 

 

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.

 

Transfer rates are excellent for a 256GB class SSD.
