Two M.2 NVMe drives in one 3.5" bay

The ICY DOCK MB834M2K-B fits two M.2 PCIe NVMe SSDs into a single external 3.5-inch device bay. It accepts drive lengths of 30mm, 42mm, 60mm, 80mm and 110mm and connects each drive through a miniSAS HD SFF-8643 interface. Tool-less installation and an adjustable locker secure every drive without screws.

Suits builds needing high-density NVMe storage

This rack is for systems with a free 3.5-inch bay and a host controller or backplane that provides two miniSAS HD ports. It is not for platforms that lack miniSAS HD connectivity or that require a different drive interface. Builders needing hot-swap trays for 2.5-inch drives should consider a different enclosure type.

Dual miniSAS HD host interface

Each M.2 slot routes to its own SFF-8643 connector, so the host must supply two miniSAS HD links to access both SSDs simultaneously. If your controller or backplane offers only one such port, only one drive will be active.

Questions about this item

How do I install an M.2 NVMe SSD into the MB834M2K-B and what step is often missed?

Slide the SSD into the tray at the correct notch for its length — 30, 42, 60, 80 or 110 mm — then close the adjustable locker until it clicks; the step people miss is forgetting to peel and stick the included thermal pad onto the controller before locking the drive.

What maintenance or replacement will the MB834M2K-B need over time?

The thermal pads supplied in the package degrade with heat cycles; replace them when you swap drives or if temperatures rise, and check that the miniSAS HD SFF-8643 cables remain firmly seated in the backplane.

What limit appears first when the MB834M2K-B runs sustained heavy I/O?

Heat builds up in the enclosed 3.5-inch bay because the tray has no active cooling; the NVMe drives will throttle once their controllers hit thermal limits unless the chassis provides strong airflow across the tray.
