Explanation

Explanation/Reference: https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/citrix-vdi-best-practices/design/design- To choose the optimal RAID level, it is necessary to consider the IOPS and read/write ratio generated by a given application or workload in combination with the individual capabilities of a RAID level. For hosting read intensive workloads, such as the Provisioning Services vDisk store,RAID levels that are optimized for read operations such as RAID 1, 5, 6, 10 are optimal. This is because these RAID levels allow read operations to be spread across all disks within the RAID set simultaneously. For hosting write intensive workloads, such as Provisioning Services write cache and Machine Creation Services differencing disks, RAID levels such as RAID 1 or 10 are optimal, as these are optimized for writes and have a low write penalty.
