We use DiskBench to time a 28.6GB block (9,882 files in 1,247 folders) of mostly incompressible random data as it's transferred from our OS array to our test drive/array. We then read from a 6GB zip file that's part of our 28.6GB data block to determine the test drive/arrays read transfer rate. The system is restarted prior to the read test to clear any cached data, insuring an accurate test result.
Write Transfer Rate
Real-World incompressible write performance is surprisingly very good.
Read Transfer Rate
Wow, look at that read transfer performance!
When writing large chunks of incompressible data, only the Samsung EVO array is able to outperform our Ultra Plus array by the slimmest of margins. This is the first array we've charted running on Windows 8.1, which could have something to do with this outcome. I guess I wasn't expecting to see our Ultra Plus array outperform the Extreme II array, when reading data, but it does.
Even though we're talking about read performance, the reason our Ultra Plus array has faster read transfers than the Extreme II array comes down to capacity. An Extreme II array of the same capacity will have slightly faster read transfers than our Ultra Plus array which you will see in an upcoming report.
