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 see the three states of performance for the select SSDs, light use, consumer steady state and worst case.

Even though the current OCZ consumer line up falls in line as they should, the performance between ARC, Vertex and Vector is so very close. On the bottom of the chart is the Crucial MX100 and it just gets beaten silly by ARC 100 when both drives are worked hard and even under light use.

Here we see the full test from start to finish. Again, ARC, Vertex and Vector are all within a sliver of each other. Only the SanDisk Extreme II and Extreme PRO drives are faster under heavy and moderate workload.

 

The 850 Pro should also be faster, but we don't have that drive tested in this capacity size yet. As a value drive, we expected the ARC 100 to fall in the bottom group, where the performance matches the price (low).
