The 73.2 GB of hard disk drive is recommended to install as system
drive in order to reduce the time to resynchronize,when the system
memory is below 20GB.
When the system memory is 20GB or more,the system Disk needs to be
146.5GB or larger. Also,300GB HDD is required when the system memory
is 48GB or more.
*The RDR resumes disk mirroring by performing quick copies of only data
changes, helping reduce the resynchronization time. However, please note that it
would be the whole copy when replacing with a new disk.
