Notes
"Compatible drive type" indicates the drives that have been tested to be compatible with Synology products. This term does not indicate the maximum connection speed of each drive bay.
The maximum raw capacity is not limited by the maximum single volume size. Synology NAS models may utilize capacities over the maximum single volume size as long as each volume created is below the limit. (Learn more)
Expansion of the internal volume is only supported if the combined single volume size does not exceed the maximum limit of 108TB.
