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 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.

The UniFi ENAS and UNAS Pro models are aimed at quite different types of storage user, even though they all sit inside the same UniFi Drive platform. The UNAS Pro, UNAS Pro 4 and UNAS Pro 8 cover the more familiar end of rackmount NAS use, including shared folders, backups, remote access, snapshots and general business file storage, with prices from $499 to $799. The ENAS costs $3,999 and moves into a much heavier class of deployment, with 16 SATA bays, 64 GB of ECC memory, ZFS, iSCSI, dual 25GbE ports, redundant hot-swappable power supplies and support for external expansion shelves.
