5.3.2 ORION (2 TB array capacity utilization, 100% random I/O and no data locality)

Because there was no locality of data reference and the utilized capacity exceeded total SSD capacity, I/O
activity was observed on both the SSD and 10K SAS drives for this completely random workload as shown in
Figure 8.
