Performance Testing

An OakGate Storage Test Platform was used to perform the majority of the performance tests conducted in this review.  You can see an article that introduces the OakGate Storage Test Platform by clicking here.

HD Tune Pro was used to perform the sustained sequential write and read tests across the whole of the drive.

The series of tests cover all aspects of performance.

Sustained Sequential Writes (HD Tune Pro)

This test performs 1024K Sequential Writes across 100% of the drives capacity (5TB). Here is the result –

 

Write b

As expected the transfer rate is greatest at the outer edge of the disk and then slows down gradually as the sequential writes progress across the surface of the disk. The average transfer rate was 131.08 MB/s.

Please note that typically the data density at the outer tracks of a hard drive is higher than the inner tracks so reading and writing will therefore occur at a higher speed.  A hard drive starts reading and writing at the outer tracks then moves towards the inner tracks.

You can see that the write speed drops of significantly towards the inner tracks. 

 

Sustained Sequential Reads (HD Tune Pro)

This test performs 1024K Sequential Reads across 100% of the drives capacity (5TB). Here is the result –

Read b

You can see that again, as expected, the Sequential Read performance drops gradually as the test progresses reading data from the outside to the inside of the disk. The average transfer rate was 131.9 MB/s.

 


Sequential Writes

This test performs Sequential Writes for 2 minutes for each combination of IO Size 0.5K, 1K, 2K, 4K, 8K, 16K, 32K, 64K, 128K, and 1024K, and Queue Depths of 1, 4, 8, 16 and 32. Here are the results –

 

 

You can see that the peak sequential write bandwidth is 170 MB/s. 

 

Sequential Reads

This test performs Sequential Reads for 2 minutes for each combination of IO Size 0.5K, 1K, 2K, 4K, 8K, 16K, 32K, 64K, 128K, and 1024K, and Queue Depths of 1, 4, 8, 16 and 32. Here are the results –

 

 

You can see that the peak sequential read bandwidth is also 170 MB/s.

Random Writes

This test performs Random Writes for 2 minutes for each combination of IO Size 0.5K, 1K, 2K, 4K, 8K, 16K, 32K and Queue Depths of 1, 4, 8, 16 and 32. Here are the results –

 

You can see that there is no scalability of performance as Queue Depth increases.

Random Reads

This test performs Random Reads for 2 minutes for each combination of IO Size 0.5K, 1K, 2K, 4K, 8K, 16K, 32K and Queue Depths of 1, 4, 8, 16, and 32. Here are the results

 

You can see that performance continues to scale all the way up to a Queue Depth of 32.

 

4K Random Mixed Reads/Writes

This test performs Mixed Random 4K Reads/Writes for many different combinations of Read/Write percentages and Queue Depths.
