Iometer - Maximum IOPS

 

Version and / or Patch Used: Iometer 2014

 

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

Mushkin's specified 71,000 read IOPS for the Reactor is very conservative to say the least. The Reactor is only outperformed by the Ignite in write IOPS. Looking at read IOPS, the BX100 has the edge for the SM2246EN controlled drives.

 

 

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 quite respectable. Slightly better write response than its twin the BX100, but the BX100 has the edge with better read response. There is likely a firmware difference between the two drives. The SM2246EN can be implemented using canned firmware or custom firmware. This is just one of the reasons the SM2246EN is today's most popular third-party controller.

 

 

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.

The Reactor and the BX100 deliver the best performance of the drives in our test pool, with a slight edge going to the BX100 in write transfer speed. This is probably the best illustration of the abysmal performance of non-Samsung TLC flash. It is also probably the best illustration of why we like the Reactor so much. Priced like TLC, but so much better.
