The TERRAMASTER D5 Hybrid is worth buying if you specifically want a 2-bay HDD/SSD enclosure plus 3 M.2 NVMe slots for £133.87, but its 3.9/5 rating from 35 reviews shows it is not a universal crowd-pleaser. At the current all-time lowest price, it is an interesting option for compact local storage, backups, or a small media or project setup where you want both spinning disks and NVMe in one box.

What makes the D5 Hybrid different?

The headline feature is the hybrid layout: 2 SATA HDDs/SSDs and 3 M.2 2280 NVMe SSDs in a single diskless enclosure. That is unusual at this price point and explains why it stands out against basic 2-bay enclosures. TERRAMASTER also claims it is the industry’s first hybrid HDD NVMe SSD enclosure, and the design is clearly aimed at users who want flexible storage tiers rather than a traditional NAS appliance.

The enclosure uses USB 3.2 Gen 2 with up to 10Gbps bandwidth, which is the right class of connection for a device like this. In practical terms, that means the external link is fast enough for a lot of home-lab tasks, but it is still a USB enclosure, not a multi-gig network NAS. If your workflow depends on shared access over the network, RAID expansion, or apps and services, this is not a Synology-style box.

How does the 2+3 RAID setup work?

The D5 Hybrid’s RAID implementation is split in two. The two tray-based drives can be configured as RAID 0, RAID 1, Single disk, or JBOD. That gives you the familiar choices: RAID 1 for redundancy, RAID 0 for speed, or JBOD/single-disk modes for flexibility. The three M.2 NVMe slots are part of the hybrid design, but the listing data only confirms the 2+3 layout and the hardware USB storage concept, so buyers should treat the enclosure as a storage device first and a true NAS replacement second.

For home lab users, that distinction matters. A RAID 1 pair in the trays could make sense for backups or a mirrored media store, while the NVMe slots are better suited to fast scratch space, active project files, or high-speed local datasets. If you want ZFS, Docker, or a full NAS operating system, this is the wrong product category.

Performance and usability

The 10Gbps USB 3.2 Gen 2 interface is the key performance limit, and that is both a strength and a ceiling. It is fast enough to justify NVMe support and should be plenty for many single-user workloads, but it will not behave like a direct-attached PCIe storage array. The tool-free tray design is a practical win: drive swaps should be straightforward, which is useful if you rotate backup disks or test different drives often.

Cooling is another important point. TERRAMASTER includes an intelligent temperature-controlled low-noise fan that automatically adjusts speed, which is reassuring for a box that can house five drives at once. That said, any enclosure with 2 HDDs and 3 NVMe SSDs has thermal management challenges, so users planning sustained writes should pay attention to airflow and drive choice.

Build quality and day-to-day use

The D5 Hybrid feels designed for convenience rather than enterprise-grade robustness. The tool-free trays, hybrid bay layout, and automatic fan control all point to a product built for easy setup and flexible desktop use. Diskless packaging also means you can choose your own drives, which is ideal if you already have spare SATA and NVMe hardware.

The main warning is that the feature mix can create expectations the product cannot meet. A 5-drive hybrid enclosure sounds like a miniature NAS, but it is still a USB storage device. If you need always-on network sharing, user permissions, package support, or remote access, a dedicated NAS such as Synology’s DS223J, DS224+, or DS224+ black model will be a better fit, even though those units cost far more at £179.97, £506.05, and £538.79 respectively.

Is it good value for money?

At £133.87, the D5 Hybrid is aggressively priced for what it offers, especially since the current price is the all-time lowest and exactly matches the recorded average. Compared with Synology’s 2-bay desktop NAS options, it is dramatically cheaper: the DS223J is £179.97, while the DS224+ models are over £500. That makes the TERRAMASTER look attractive if your priority is local storage capacity and hybrid flexibility rather than NAS software.

The value case is strongest for enthusiasts who already understand the trade-offs. You are buying hardware flexibility, not a polished ecosystem. The 3.9/5 rating from 35 reviews suggests the product delivers enough for many buyers, but not enough to erase concerns about expectations, polish, or edge-case reliability.

What should you watch out for?

The biggest downside is that this is not a full NAS and should not be treated like one. It also has a relatively modest review score for a storage device, which suggests some buyers have run into issues or mismatched expectations. The other practical concern is that hybrid enclosures can become awkward to manage if you want everything to behave like one clean storage pool; the 2-drive RAID area and 3 NVMe slots may suit different roles rather than one unified workflow.

If you want a simple, fast, diskless enclosure for mixed SATA and NVMe storage, the D5 Hybrid is compelling at £133.87. If you want network services, app support, or a more mature NAS experience, the Synology alternatives are more expensive but better aligned with that job.
