TERRAMASTER D5 Hybrid 2+3 Bay Drive Enclosure

Hybrid 2+3 Bay Enclosure

The TerraMaster D5 Hybrid combines two 3.5-inch SATA drive bays with three M.2 2280 NVMe slots in a single USB 3.2 Gen 2 enclosure. It targets users who want high-capacity hard drives for cold storage alongside fast NVMe SSDs for active workloads. The hardware RAID controller manages the two SATA bays independently from the NVMe slots. It is not suited for buyers who need RAID protection across all five drives simultaneously.

USB 3.2 Gen 2 10Gbps Interface

The USB 3.2 Gen 2 connection caps total throughput at 10Gbps, shared across every installed drive. With two SATA hard drives in RAID 0 the enclosure reaches 521MB/s, while two SATA SSDs in RAID 0 hit 960MB/s. A single NVMe SSD can deliver up to 980MB/s, but simultaneous heavy traffic on multiple drives will contend for the same 10Gbps pipe. Builders requiring sustained multi-drive bandwidth beyond this limit should look elsewhere.

Hardware RAID on SATA Bays Only

The two SATA trays support RAID 0, RAID 1, JBOD and Single Disk modes handled by the enclosure's own controller. The three M.2 NVMe slots operate strictly as individual single disks with no hardware RAID option. This split architecture decides whether the D5 Hybrid fits a given workflow: it works when you want mirrored or striped bulk storage plus separate fast scratch disks, but it cannot stripe or mirror the NVMe drives themselves.
