The ENAS is the enterprise step in the UniFi NAS range. Earlier UNAS devices made sense for straightforward storage, easy deployment and UniFi-integrated file services, but they did not fully compete with business NAS platforms from QNAP, Synology, TrueNAS-style servers or other ZFS-capable rackmount systems. ENAS changes that conversation by adding the hardware and software features business buyers were waiting for: more bays, ZFS, 25GbE, ECC memory, iSCSI and redundant power. It also feels very clearly derived from Ubiquiti’s enterprise rack hardware design language. The 3U chassis, front di

UniFi-heavy businesses that want storage managed in the same general ecosystem as their network. Rackmount storage buyers who need more than the UNAS Pro family can offer. Virtualisation and block-storage users who need iSCSI targets rather than only SMB/NFS shares. Multi-user teams that can actually use 25GbE uplinks, hot spares, snapshots and expansion. Administrators who value simpler management over the deepest possible enterprise storage interface.

Businesses that need a single large UniFi-managed storage platform. Sites planning around ZFS, RAID-Z, snapshots, iSCSI or immutable storage workflows. Deployments with 25GbE switching and multiple high-speed clients. Buyers who expect to add expansion shelves rather than replace the NAS later.

The UniFi memory surcharge is an additional fee shown separately on affected Ubiquiti / UniFi product pages or during checkout. Rather than changing the headline MSRP alone, Ubiquiti has itemised an additional surcharge against selected products. According to the surcharge schedule reproduced by NASCompares, the adjustment is tied to volatility in memory and storage markets, with part of the additional cost absorbed by Ubiquiti and part passed through as a separate line item. This matters because UniFi hardware is used across gateways, WiFi access points, switches, Protect cameras/NVRs, Talk h
