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

MDD doesn't list random 4k read/write performance for the BP5e, but we can say it's up to 102K/77K.

 

 

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.

Response times are as expected for a TLC SSD.

 

 

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

This is the unmasked write performance of S10 powered Toshiba 15nm TLC Flash. We are pleasantly surprised. The BP5e has much-better-sustained write performance than any of the competing TLC SSDs in our test pool.
