The maximum raw storage capacity available by connecting QNAP expansion enclosures:
|QNAP NAS Model||QNAP Expansion Enclosure||No. of Expansion Enclosures||Total HDD No. (NAS + Enclosure)||Max. Raw Capacity (TB)**|
*RAID groups of storage pools cannot cross multiple enclosures.
**The maximum capacity is calculated by using 10TB HDDs.
Note: You can create a volume over 16TB, but its storage space cannot be expanded. Volumes smaller than 16TB can only be expanded up to 16TB by using online capacity expansion. For the best use of storage space on your NAS, please create multiple volumes.
