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 get our first look at the 850 Pro running Samsung's latest version of RAPID Mode. Our test uses has 16GB of DRAM so 4GB goes to the cache system. RAPID Mode enhances light and moderate use performance but under heavy loads it actually reduces the storage system performance. We'll talk more about this on the next page.

 

Without RAPID Mode, the 850 Pro outperforms everything else on the chart including the SanDisk Extreme II 120GB, it closest competition from a performance standpoint. SanDisk didn't release an Extreme PRO in the 128GB capacity size so Samsung gets to dominate this size.

 

Storage Bandwidth - All Tests

Here we see all of the stages of the test. Let's tackle the 850 Pro 128GB without RAPID enabled first. As you can see the 850 PRO 128GB runs faster than the other 128GB capacity size drives in this important test that shows real-world performance using a wide range of applications. The results are averaged out, and then charted by the state of the flash. The 850 Pro 128GB is faster all the way down the line.

 

With RAPID Mode enabled, the light use performance is very high; it towers over the other results on the chart. This is a throughput test so data transfers are only shown on this chart. The RAPID Mode performance is a lower because the data going to the drive comes from both the DRAM and the system so the results are off a bit. Let's look at latency though.
