UniFi - Storage Requirements and Compatibility – Ubiquiti Support and Help Center

Though not required for normal operation of most UniFi OS consoles, HDDs enable the storage of recordings from Protect and Access, and voicemails from Talk. An HDD is required for the Cloud Key G2+, so they come pre-installed with a 1TB disk for your convenience.
