Multithreaded Read & Write Patterns
The multithreaded tests simulate a situation when there are one to four clients accessing the hard disk at the same time – the clients’ address zones do not overlap. We will discuss diagrams for a request queue of 1 as the most illustrative ones. When the queue is 2 or more requests long, the speed doesn’t depend much on the number of applications.

The Force and Reactor drives are somewhat better than the others at multithreaded reading. The Indilinx-based models accelerate at four data threads. This is not the first time we note this peculiarity of the Indilinx controller.
The Reactor is surprisingly the best at multithreaded writing. Based on a simple JMicron 612, it beats the SSDs with much more advanced controllers. The Force is more or less good, yet can yield more than 100 MBps at two threads only. In the Extreme series the SSDs are ranked according to their storage capacities, the Nova taking an in-between position, whereas the junior Performance model is always ahead of the senior model from the same series.
