Random Read and Write Performance

In order to be able to properly interpret the results acquired from the compatibility tests of the Seagate® Exos® X18 drive while it was used as a data storage device for Open-E JovianDSS, we would like to illustrate the performance results of random writes (Chart 1) and reads (Chart2).
