Two-slot M.2 NVMe mobile rack
The ToughArmor MB852M2PO-B accepts two M.2 PCIe NVMe SSDs in lengths from 2230 to 22110 and mounts inside a 9.5 mm ultra-slim optical drive bay. It targets server or workstation builders who want high-speed solid-state storage without using a standard drive cage or PCIe slot.
OCuLink Gen 4 connectivity and thermal tray
Two PCIe 4.0 OCuLink connectors compliant with the SFF-9402 pinout deliver up to 64 Gbps of bandwidth per drive. A built-in thermal pad transfers heat from each SSD to the metal tray, helping maintain consistent performance during sustained workloads.
ODD-bay form factor limits expandability
The 9.5 mm bay height restricts the assembly to two drives and prevents the use of thicker cooling solutions or additional controllers. Systems without a compatible optical bay or spare OCuLink ports cannot use this rack, and the design does not support Tri-Mode operation.

Questions about this item
What PCIe generation and connector does the ToughArmor MB852M2PO-B use, and what throughput does it cap at?
It uses two PCIe 4.0 OCuLink connectors that support up to 64Gbps transfer speed.
Which drive bay size and drive lengths does this mobile rack accept?
It installs in a 9.5mm ultra-slim ODD bay and fits M.2 NVMe SSDs in 2230, 2242, 2260, 2280 and 22110 lengths.
How is the rack mounted and what step is commonly missed during installation?
Slide the rack into the 9.5mm ODD bay and secure it with the bay screws; the step often missed is removing the protective film from the built-in thermal pad so it contacts the SSD.
