Why each option
RAID 1 implements data mirroring to provide fault tolerance, which is critical for ensuring high availability and minimizing vDisk inconsistency in a Citrix Provisioning Services environment.
RAID 1 does not provide striping; its primary mechanism is mirroring data across disks for redundancy.
While RAID 1 can offer good read performance, it generally does not provide the highest performance compared to striping-based RAID levels like RAID 0 or RAID 10.
RAID 1, or mirroring, duplicates data identically across two physical disks. If one disk fails, the other contains a complete copy, ensuring continuous operation and preventing vDisk data loss, thus providing fault tolerance and high availability for the PVS solution.
RAID 1 requires twice the disk space as the data stored, dedicating 50% of total capacity to redundancy, meaning it does not minimize disk usage.
