ASRock Z97 Extreme6 PCIe Ultra M.2 Storage Performance Overview

Futuremark PCMark 8 Extended – Consistency Test

 

Version and / or Patch Used: 2.0.228

 

Heavy Usage Model:

 

FutureMark's PCMark 8 allows us to wear the test drive down to a reasonable consumer steady state and then watch the drive recover on its own through garbage collection. To do that, the drive gets pushed down to steady state with random writes and then idle time between a number of tests allows the drive to recover.

 

Precondition Phase:

1. Write to the drive sequentially through up to the reported capacity with random data.

2. Write the drive through a second time (to take care of overprovisioning).

 

Degradation Phase:

1. Run writes of random size between 8*512 and 2048*512 bytes on random offsets for 10 minutes.

2. Run performance test (one pass only).

3. Repeat 1 and 2 for 8 times, and on each pass increase the duration of random writes by 5 minutes.

 

Steady state Phase:

1. Run writes of random size between 8*512 and 2048*512 bytes on random offsets for 50 minutes.

2. Run performance test (one pass only).

3. Repeat 1 and 2 for 5 times.

 

Recovery Phase:

1. Idle for 5 minutes.

2. Run performance test (one pass only).

3. Repeat 1 and 2 for 5 times.

 

Storage Bandwidth

 

PCMark 8's Consistency test provides a ton of data output that we use to judge a drive's performance.

Here we can gauge how close the performance is with an adapter on a Z87 system and the drive directly in the Z97 Extreme6. The performance is very close over a wide range of tests that take nearly 24 hours.

 

Storage Bandwidth All Tests

 

Here we see all of the tests plotted on the same chart. This shows the drive from worst case to steady state to recovery performance.

It's not difficult to spot the two tests with the XP941; they are at the top of the chart outperforming the other SSDs.
