PCMark 8’s Consistency test provides a huge amount of performance data, so here we’ve looked a little closer at how the WD SN550 performs in each of the benchmarks test suites.

Adobe Creative Cloud

The drive gets hit hard during the Adobe CC test phases and although the bandwidth trace for the two PhotoShop traces is quite smooth, the actual bandwidth is pretty low and the Recovery phase is very erratic. The other apps suffer throughout the Degradation and Steady-State phases. The best recovery phase in terms of stability is for the Indesign trace.

Microsoft Office

Usually, in the MS Office test, it's the Word trace that causes a drive problems. Although in the case of the SN550 the bandwidth is pretty low during the test run, it's fairly consistent which is something you can't say about the Excel and PowerPoint traces which seem to cause the drive real problems.

Casual Gaming

The SN550 handles the World Of Warcraft trace much more efficiently than the Battlefield 3 one, whose performance is very erratic.
