Ubiquiti Enterprise NAS (ENAS): The 16-Bay Rack NAS Explained (2026 Australian Guide)

Sixteen drive bays, dual 25G SFP28, redundant hot-swap power — Ubiquiti's first true enterprise storage chassis, explained for Australian buyers.

With the Enterprise NAS, Ubiquiti stops playing at storage. Sixteen hot-swap drive bays, dual 25 Gbps networking, NVMe caching bays, Mini-SAS expansion and redundant hot-swappable power — a 3U chassis aimed squarely at server rooms that until now bought QNAP, Synology or TrueNAS hardware. In Australia the UniFi storage range is supplied by ARC IP Networks, an authorised Ubiquiti reseller — genuine stock, full manufacturer warranty.

Ubiquiti Enterprise NAS (ENAS) 3U rack-mount 16-bay network storage chassis

What is the Enterprise NAS?

The Enterprise NAS (model ENAS) is the top of Ubiquiti's network-storage line — a 3U rack chassis holding sixteen 2.5″/3.5″ SATA drives plus two M.2 NVMe bays, driven by an eight-core Arm processor with 64 GB of memory and a 4.7″ front touchscreen. Where the existing UNAS Pro and UNAS Pro 8 serve offices, the ENAS is built for the rack room: dual 25G SFP28 uplinks, hot-swappable redundant power supplies, and two Mini-SAS ports that daisy-chain Ubiquiti's Enterprise Storage Expansion shelves — sixteen more bays per shelf — when you outgrow the chassis.

Why it matters

UniFi shops have always had to leave the ecosystem for serious storage. The ENAS closes that gap — one vendor, one management plane, from the access point to the archive.

What you need to run it

To use those 25G uplinks you'll want SFP28-capable aggregation — see our UniFi switching range — plus enterprise-grade drives (Ubiquiti offers matched HDDs, or bring your own NAS-rated disks). If the ENAS will hold camera archives, our storage sizing guide helps you do the retention maths, and the Protect NVR comparison covers the recording side.

Frequently asked questions

What is the Ubiquiti Enterprise NAS?

The Ubiquiti Enterprise NAS (model ENAS) is a 3U rack-mount network storage chassis with sixteen 2.5/3.5-inch SATA drive bays, two M.2 NVMe bays, dual 25G SFP28 plus 10GbE RJ45 networking, Mini-SAS expansion ports and redundant hot-swappable 550W power modules — Ubiquiti's largest and most serious NAS to date.

How many drives does the Enterprise NAS hold?

Sixteen hot-swappable 2.5-inch or 3.5-inch SATA HDDs or SSDs, plus two M.2 NVMe SSD bays, and it can grow further: two SFF-8644 Mini-SAS expansion ports connect Ubiquiti's Enterprise Storage Expansion units, each adding another sixteen bays.

What network speed does the Enterprise NAS support?

Two 25 Gbps SFP28 ports (which also run at 10G or 1G) and one 10 GbE RJ45 port that supports 10G, 5G, 2.5G, 1G and 100M — so it pairs naturally with a UniFi aggregation switch over SFP28.

Is the Enterprise NAS available in Australia?

Ubiquiti has just announced the Enterprise NAS, and Australian availability is rolling out. ARC IP Networks (arcip.com.au), an authorised Ubiquiti reseller in Australia, supplies the UniFi storage range as genuine Australian stock with full manufacturer warranty — contact them to be notified when the ENAS lands.

What is the difference between the Enterprise NAS and UNAS Pro 8?

The UNAS Pro 8 is a 2U, eight-bay NAS with 10G networking aimed at businesses; the Enterprise NAS is a 3U, sixteen-bay chassis with 25G networking, NVMe bays, Mini-SAS expansion and redundant power — built for server rooms where storage, throughput and uptime all need headroom.
