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.

 

PCMark 8's Consistency test provides a ton of data output that we use to judge a drive's performance. Here we see the three states of performance for the select SSDs, light use, consumer steady state and worst case.

 

Storage Bandwidth - All Tests

The SM951 showed complete dominance up to this point in the synthetic tests and this next set of charts will show real-world performance with real consumer application workloads. Again, the SM951 surpasses the other native PCIe M.2 devices on the market, and not by just a smaller incremental margin either.

 

Storage Bandwidth - Heavy Load

Under heavy workloads the SM951 nearly quadruples the M6e products. The XP941 products hold up well under heavy loads, but nowhere near the same level as the SM951.

 

Storage Bandwidth - Typical Consumer Load

In typical consumer workloads, the margin shrinks, but the other products are still well under the performance of the SM951.
