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 All Tests

 

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.

When it comes to performance consistency with real-world workloads, the Phoenix Blade 480GB takes top honors when compared to our other PCIe all-in-one RAID devices. Here we see all of the tests, but in all of the states.

 

 

Prosumer / Heavy Workloads

In the prosumer workloads where the drives are hit hard with many data writes with little to no time to recover, the G.Skill Phoenix Blade shows a significant advantage in throughput.

 

 

Typical Consumer Workloads

The built-in SCSIunmap command recognition allows the Phoenix Blade to recover from the heavy loads and still keep its performance lead even in the typical consumer levels of stress to the drive.
