Mirroring

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.
