| Disk latency to device with a MySQL slave running providing backround IO. | |
| The SSD's are sd{5,6,7,8}, sd{0,1,2,3} are Hard drives | |
| Times are in microseconds and the aggregation is per device and operatins type READ/WRITE | |
| For refernece the Intel datasheet http://www.intel.com/content/www/us/en/solid-state-drives/ssd-dc-s3710-spec.html | |
| states that reads should return from the device in 55 microseconds, and writes in 66 microseconds, for 4KB block sizes. | |
