Performance Tests

We used a reference Dell Optiplex 760 featuring Intel Q35 Express chipset and 2.8Ghz Core 2 Duo CPU and 2Gb for the performance tests. We included the performance results of one of the top performing USB tested in the past on our previous * test setup, the Kingston DataTraveler HyperX 4GB.

We start of with a simple random access test in HD Tach 3.0



Over USB the Throttle scores quite well, switching to eSATA halves the random access time again, well below 1 millisecond.



Concentrating on the USB performance first, the Throttle is almost on par with the HyperX in average read speed. Once connected to the eSATA port the performance easily doubles, with the burst speed closing in on the claimed 90Mb/s.

ATTO HDD Benchmark v2.34 allows for read and write tests using different file chunk sizes, allowing you to see how performance scales:



Using the USB interface the Throttle in not able to best the HyperX in raw larger file chunk size, trailing by ~6Mb/s in the read test. The eSATA interface proves vastly superior here, especially with smaller file chunks the performance is 4-5x higher compared to USB. Once large file chunks are reached the performance is surpassing 90Mb/s !

Onto the write tests:



OCZ mentions write speeds of ~30mb/s, from our results we can see that over eSATA the Throttle already surpasses this claim at 8k file size chunks, and this flash drive is able to pass the 50Mb/s mark!

Switching to USB the Throttle is noticeably slower, averaging ~18Mb/s and trailing the HyperX again.
