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 ten minutes.

2. Run performance test (one pass only).

3. Repeat 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 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.

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

Here we get our first taste of PlexTurbo 2.0 in a system with 16GB of DRAM. When you have 16GB or more of system DRAM, Plextor's software will ration 4GB to make a DRAM cache for your SSD.

PlexTurbo is new; it just released this past August with the M6 Pro 2.5" SSD. It didn't take long for Plextor to reshape the software and give it the 2.0 name.

Storage Bandwidth - Heavy Load

Under heavy load, PlexTurbo 2.0 doesn't give us much of a performance upgrade. In some places, we even measured a performance decrease. This isn't unheard of - Samsung's Magician software does the same thing under heavy workloads.

Storage Bandwidth - Typical Consumer Load

Both pieces of software are designed for consumer workloads, so using the software with the drive in steady state doesn't increase throughput performance. In the consumer tests shown here, the software does provide a small improvement in throughput performance.
