Corsair Neutron XT SSD Preview

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.

 

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

This test uses incompressible data so Phison's compressible performance increase magic is ineffective here.

 

Storage Bandwidth - Heavy Load

Let's start out with the heavy workload tests with the drives under heavy use. The Neutron XT clearly performs better than a number of products on the market today, but in the same vein, it is clearly a bit slower than the Extreme PRO 960GB and 850 Pro 1TB.

 

Storage Bandwidth - Typical Consumer Load

When we move into light use workloads, things change quite a bit. The Extreme PRO and 850 Pro are still at or near the top of the list, but the SLC areas from the flash translation layer allow several of the value SSDs to increase performance to levels higher than the Neutron XT.

 

FTL SLC area is nearly industry wide with Samsung, SanDisk, OCZ, Toshiba and most recently Micron using the technology. We're surprised Phison didn't use it in some form - it's not like the S10 lacks processing power.
