Our BX100 has no issues meeting and exceeding Crucial's max random IOPS spec. of 80K/70K.

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 is run twice for 30 seconds consecutively, with a 5-second ramp-up before each test. The test drive/array is partitioned and attached as a secondary device for this testing.

Average Disk Response

As expected, the BX100 has slightly higher response times than the rest of our premium drives.

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) of mostly incompressible 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 drives read transfer rate. Our system is restarted prior to the read test to clear any cached data, ensuring an accurate test result.

We're pleasantly surprised to see such good transfer performance from our BX100. How can this be you ask? Micron/Crucial has a little magic sauce built into their current flash. This third-generation magic sauce is called "Native Write Acceleration" technology.
