The maximum raw storage capacity available by connecting a QNAP expansion enclosure:
| NAS Model | RAID Expansion Enclosure | No. of RAID Expansion Enclosure | Total HDD No. (NAS + Enclosure) | Max. Raw Capacity (TB)*** |
|---|---|---|---|---|
| TS-451+ | UX-800P | 1 | 12 | 96 |
| UX-500P | 1 | 9 | 72 |
*To expand the storage space with an UX expansion enclosure, please create a separate static volume or storage pool on the UX expansion unit.
**RAID groups of storage pools cannot cross multiple enclosures.
***The maximum capacity is calculated by using 8TB HDDs.
