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 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 ten minutes.

2. Run performance test (one pass only).

3. Repeat steps one and two, eight times, and on each pass increase the duration of random writes by five 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 steps one and two, five times.

Recovery Phase:

1. Idle for five minutes.

2. Run performance test (one pass only).

3. Repeat one and two, five 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.

In this test, we look at consumer performance consistency, and consider how long workloads effect drive performance. For most of us, the orange bar is what we should see in daily use scenarios. Heavier consumer workloads (blue bar), and less intense workloads (red bar), are also shown on this chart.

Storage Bandwidth All Tests

Here we see all of the tests, including those that took the drive down into steady state. The 530 starts off in the middle of the chart that compares several drives.

Typical Consumer Bandwidth

intel_530_series_480gb_ssd_review_66

Here we highlight the typical consumer light use section of the chart. In the other tests, the 530 Series 480GB delivered mediocre performance, but here the drive falls to the bottom of the group in daily use program performance. The only issue with testing SandForce based SSDs with this test is the compressible vs. incompressible factor. This series of tests uses 100% incompressible data, even though the original software wouldn't be 100% incompressible.
