Best 5-Bay DAS Enclosures: Compare RAID, Capacity and Price
Compare current five-bay DAS and RAID enclosures from UGREEN, TerraMaster, ORICO, Yottamaster and other brands. See current price, price per bay, interface, RAID support and drive compatibility.
A fifth bay can improve capacity efficiency in RAID 5, provide room for a hot spare or let a hybrid enclosure combine HDD and NVMe storage. The best five-bay product is the one whose controller, interface and cooling match the intended array, not simply the one with the largest total-capacity claim.

What the fifth bay changes
Five bays give a storage planner more choices than the common four-bay format. In RAID 5, five matching drives provide roughly four drives worth of usable capacity. The extra bay can also hold a spare, a separate backup disk or a different tier of storage when the enclosure supports individual modes. Some hybrid products describe five total slots but split them between SATA drives and M.2 NVMe SSDs.
Count the actual drive types. A two-SATA plus three-NVMe hybrid is not interchangeable with a five-HDD enclosure. Cloudzat records SATA and NVMe bay counts separately when the listing provides enough information.
RAID 5 is common, but verify the controller
Five-bay enclosures often advertise RAID 0, 1, 5, 10, JBOD and proprietary span or clone modes. RAID 5 is attractive because it uses one drive worth of parity, but the quality of implementation matters. Look for documented rebuild behavior, clear status indicators and a utility or switch system you can understand before data is loaded.
Some five-bay products expose independent disks and rely on the host for software RAID. That can be a valid design, especially on a dedicated workstation or server, but it should not be mistaken for a hardware array. If the host changes, software compatibility can become the deciding factor.
Capacity claims and drive limits
A five-bay product advertised for 100TB may be assuming five 20TB drives. Newer models may claim larger totals as drive validation changes. Check both the maximum per drive and the maximum total. The controller, firmware, partition scheme and operating system can all influence practical support.
For long-lived storage, buy enough capacity for growth without filling every bay unnecessarily. If expansion is not supported, adding a drive later may require copying data elsewhere and recreating the array.
Interface bandwidth for five drives
Many consumer five-bay RAID boxes use a 5Gbps USB-C link. That may be adequate for sequential HDD workloads, but it can become a bottleneck for several SSDs or a fast RAID 0 array. A 10Gbps interface offers more headroom. USB4 and Thunderbolt products serve higher-performance niches and generally cost more.
The listed link speed is not the same as measured storage performance. Controller design, parity calculation, drive media and queue behavior affect the result. Evaluate the workload rather than buying the largest protocol number.
Power and cooling are central at five bays
Five HDDs can draw substantial startup power and create steady heat. Use the supplied external power supply, and make sure it is rated for the exact model and region. Avoid replacement adapters selected only because the plug fits. Look for active cooling, unobstructed airflow and a fan that can be serviced if the enclosure will run continuously.
Large arrays may sit near a desk or media server, so noise matters. The total acoustic profile includes fan tone, drive seeks and vibration through the chassis. A heavier enclosure with secure trays can sometimes sound quieter than a lightweight plastic box using the same disks.
UGREEN and TerraMaster approaches
UGREEN sells five-bay USB-C RAID products that advertise multiple controller modes and large SATA capacity. TerraMaster offers both conventional multi-bay DAS devices and hybrid designs that combine SATA and NVMe slots. Their products do not all provide the same RAID behavior, even when the bay count is similar.
Use brand pages to compare the current models, then open the official specification for the exact SKU. Regional product revisions and bundle options can change the included cables, capacity validation and warranty.
Best workloads for five bays
A five-bay HDD array is useful for large media libraries, workstation backup, photo archives and capacity-focused local storage. Video editors can use a faster model for active projects, while keeping a second backup elsewhere. A hybrid DAS can separate hot NVMe work files from colder HDD storage, but it is not automatic tiering unless software is configured to move data.
Plex itself does not require high storage bandwidth for ordinary streaming, but a large library benefits from capacity, reliability and simple maintenance. The server still needs to be running because a DAS does not provide network services independently.
Buying checklist for a five-bay unit
Verify the number and type of bays, RAID levels, controller method, link speed, maximum drive size, cooling, hot-swap rules, operating-system support and whether the product is diskless. Read the reset or mode-change instructions before configuring an array because changing modes often erases every installed drive.
Compare price per bay and total system cost. The cheapest enclosure can become expensive if it requires paid RAID software, unsupported adapters or a full set of new drives to achieve the intended layout.
Quick decision guide
Capacity-first build
Five matching CMR HDDs in a supported RAID 5 layout can deliver strong usable capacity.
Hot and cold storage
A hybrid product can keep active files on NVMe and archives on HDD, but software must manage the workflow.
Future expansion
Leave a bay unused only if the enclosure supports adding it later without destroying the existing array.
Quiet desktop use
Compare fan design, chassis material and drive acoustics, not only the advertised noise number.

Frequently asked questions
Why choose five bays instead of four?
The extra bay can increase RAID 5 usable capacity, provide a spare or support a hybrid storage design.
Can RAID 10 use five drives?
Traditional RAID 10 uses an even number of drives. A five-bay enclosure may use four drives for RAID 10 and leave one separate or spare, depending on the controller.
Are all five-bay enclosures hardware RAID?
No. Some provide independent disks or software RAID only. Confirm the exact controller and modes.
Is 5Gbps enough for five HDDs?
It can be adequate for many HDD workloads, but faster striped arrays or SSDs may benefit from 10Gbps or more.
Can I mix SATA HDDs and SSDs?
Use separate volumes unless the manufacturer explicitly supports the mixed layout. A mixed RAID generally inherits the smallest and slowest characteristics.
Does a five-bay DAS replace a NAS?
No. A DAS depends on the connected computer. A NAS operates independently and serves data over a network.
