What if we expand from RAID 1 to RAID5, what will be the maximum drive number per RAID?
Do we have the opportunity to set the maximum number of RAID to 12?
I'm planning to expand my RAID1 currently with two disk arrays, to a RAID6 with eight disk arrays.
On Synology NAS models that support RAID Group, there can be multiple RAID arrays in a RAID 5, RAID 6, or RAID F1 storage pool.
RAID arrays belonging to the same storage pool will be of the same RAID type, which means RAID 5, RAID 6, or RAID F1.
The maximum number of drives for each RAID array can be 6, 12, 16, 20, or 24. You can set the maximum number of drives while creating the storage pool, and the number cannot be modified later.
When a RAID array has been assigned with the maximum number of drives, the next drive added to the storage pool may be assigned to a new RAID array. The new RAID array must contain the minimum number of drives required for that specific RAID type (i.e., three drives for RAID 5 and RAID F1, and four drives for RAID 6).
