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

We test NVMe SSDs using eight threads at QD32 (QD256). We do this because we want to see what the drive can generate at its maximum attainable queue depth.

 

Another lab record goes to the 970 Pro in jaw-dropping fashion. This time for the highest IOPS from any flash-based consumer SSD we've tested.

 

 

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.

Although the 970 Pro delivers by far the best-read response of any SSD on this chart it is not the best ever for a flash-based SSD. That title belongs to ADATA's SX8200 480GB. SanDisk's Extreme Pro delivers by far the best write response we've seen from any SSD including Optane.

 

DiskBench - Transfer Rate

 

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 Toshiba RD400 1TB 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. We consider write transfers to be more important than read transfers.

The 970 Pro sets a new lab record for read transfer rate. Samsung's 970 EVO delivers the highest write transfer rate for any consumer SSD we've ever tested.
