Hyperstone U9 Flash Controller Deep Dive (Page 3)

Testing Notes

We grabbed a handful of common user applications to run storage-focused tests on the five devices that survived our synthetic testing. The applications tests come from the UL PCMark 8 suite and measure the amount of time it takes to complete simple and complex tasks. The final chart on this page shows the combined results from the individual tests with a single throughput score that is easy to compare.

Game Testing


At first, you may not think of gaming as a relevant use case for the Hyperstone U9, but many of these drives find homes in casino gaming. In Las Vegas, you will see the gaming machines playing videos and moving through complex lighting patterns. Under the surface, these machines record video and log player data. The IO mix is similar to consumer gaming applications like used in these two tests.

Photoshop Testing


Photoshop reads in large sequential data blocks, but the manipulations in the images push the IO in different directions, including random reads and writes. The two Hyperstone drives breeze through the two Photoshop workloads with ease.

Additional Adobe Testing


These three tests are somewhat repetitive. The important takeaway in this series is how much faster the two Hyperstone drives complete the workloads compared to the consumer-grade products.

Microsoft Testing


The three Microsoft tests are much lighter than the Adobe tests, so they don't provide a lot of insight into industrial use. These tests do show performance in office environments. The U9's advanced encryption, error correction capabilities, and high random performance open the door for enterprise Windows To Go use.

Total Application Storage Bandwidth


The total storage bandwidth chart averages the throughput of the other tests on this page. The Hyperstone U9 programmed with pSLC walks away from all of the other products and delivers the highest throughput for any native USB drive we've tested. The MLC model delivers around half the performance in Windows applications.
