Are vibrations killing enterprise disk performance?

According to this paper by Julian Turner, anti vibration devices such as the AVR 1000 can yield impressive enterprise storage performance gains.

I am quoting the paper here:

” However, there was a shocking 246% performance difference for the RandomRead1m test and a 56% and 61% difference for the Random Read 2k and 8k tests respectively. The performance difference of Random Writes was similarly compelling with 52% difference for the 2k case, 88% difference for the 8k case, and 34% difference for 1m test.

Sequential IO only improved by about 10/15% though. ZDNET has a good summary here. And they have a good point: if random IO for regular disks can be improved by 50%, that is not good news for SSDs.
