Good to know

Drives are not included; you can install up to four SATA HDDs or SSDs for a maximum raw capacity of 80 TB (using 20 TB drives). The device is managed through the UniFi Network Application via Ethernet in-band, so no separate management port is needed. A rackmount kit is included for immediate installation.
