| Notes |
- Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored.
- Each internal volume (may consist of multiple drives) is expandable up to 108TB.

| Notes |
- Regarding data concerning tests with RAM expansion, all memory slots are installed with the maximum capacity of supported RAM.
- The testing standard was based on the maximum number of concurrent connections supported by this model. During the testing, 25% of the connections were used to transfer files concurrently. The transfer process guaranteed that the connections were not interrupted; the minimum transfer speed was not guaranteed.
