[Hydra LCM] Do you have more detailed information about the RAID 5 array?

In RAID 5 mode, the user data is striped across two or three disks (depending on how many are in the set) and parity is calculated for the final disk. However, the data and parity locations are not fixed and the parity moves across the disks.

The RAID controller inside the Hydra Super-S LCM is using a backward parity rotation and the RAID stripes are 512 sectors, so all disks are accessed in a balanced manner and the parity disk has no additional workload.
