7. iSCSI ReadyTIER RAID Performance
We repeated the following tests, but with ReadyTIER added:
• Random read and write performance
• Sequential read and write performance
7.1. Random Read and Write Performance on iSCSI Volumes
The figure below shows that the ReadyTIER volume outperforms RAID volumes in the random read and write tests.

7.2. Sequential Read and Write Performance on iSCSI Volumes
The figure below shows that both a RAID 60 volume and a RAID 6 volume outperform a volume with ReadyTIER during the
sequential read and write test.
