Black metal 4-bay M.2 NVMe enclosure for 5.25 inch bay with four OCuLink ports

ICY DOCK

ICY DOCK ToughArmor MB720MK-B V3 4-bay M.2 NVMe rack server

SKU CH-Y30E-V8RP3

Holds four M.2 NVMe drives up to 110 mm in a single 5.25" bay with four SFF-8612 OCulink links at PCIe 4.0 speeds

  • TypeRack
  • Holds four M.2 NVMe SSDs of all lengths from 30mm to 110mm
  • Fits a standard external 5.25" optical drive bay
  • Connects via four OCuLink SFF-8612 ports for PCIe 4.0 host interface
  • Supports PCIe 4.0 transfer rates up to 64Gb/s per drive bay
  • Tool-less screw-less adjustable locker enables quick drive maintenance

4-Bay M.2 NVMe Rack

The ICY DOCK ToughArmor MB720MK-B V3 installs into a standard external 5.25 inch optical drive bay and holds four M.2 NVMe solid-state drives. It accepts lengths of 30mm (2230), 42mm (2242), 60mm (2260), 80mm (2280), and 110mm (22110). The full-metal enclosure meets flammability requirements and connects to the host via four SFF-8612 OCuLink ports.

Suits builders with NVMe host and 5.25 bay

This unit serves administrators and integrators who need dense, hot-swappable NVMe storage in a 5.25 inch bay and have a Tri-mode controller or NVMe host with OCuLink connectivity. It is not suited for systems lacking an NVMe-capable host interface, for chassis without a 5.25 inch bay, or for installations requiring more than four drive slots.

PCIe 4.0 x4 per bay via OCuLink

Each bay delivers PCIe 4.0 x4 bandwidth up to 64Gb/s through its dedicated OCuLink connection. The screw-less adjustable locker secures every supported drive length without tools. Verify that the host controller provides PCIe 4.0 and sufficient OCuLink ports before purchase.

Questions sur cet article

Which M.2 lengths does the MB720MK-B V3 accept?

The enclosure holds 2230, 2242, 2260, 2280 and 22110 modules, so every common M.2 NVMe size fits without adapters.

What does the 64 Gb/s per bay figure mean when the unit is installed?

Each bay runs at PCIe 4.0 x4, delivering up to 64 Gb/s of raw bandwidth to a single NVMe drive when the host controller supports that speed.

How does the OCuLink SFF-8612 interface limit performance in practice?

Four SFF-8612 ports each carry one PCIe 4.0 x4 link, so the connection caps each drive at the 64 Gb/s lane rate rather than the enclosure itself.
