Mobile Storage Rack RAIDSONIC ToughArmor MB842MP-B — 2 Removable Slots for M.2 NVMe, PCIe 4.0 x16

The RAIDSONIC ToughArmor MB842MP-B is a mobile storage rack for two removable M.2 NVMe drives that installs into a PCIe 4.0 x16 slot. It provides a compact, hot-swappable solution for adding high-speed NVMe storage to servers, workstations and industrial PCs without exposing internal drive bays. Designed to enable quick drive replacement and serviceability, the unit preserves system uptime while allowing easy maintenance and storage expansion.

Advantages

The design supports two removable M.2 NVMe modules and connects via a PCIe 4.0 x16 interface, enabling high-bandwidth data transfer where the host system provides PCIe lanes for NVMe operation. The mobile rack format allows drives to be inserted and removed without opening the chassis, simplifying drive swaps and reducing service time. The product is suitable for compact installations and environments where continuous operation and rapid drive access are important.

Suitable for

• Servers requiring hot-swappable NVMe storage
• Workstations needing compact high-speed storage expansion
• Industrial PCs or embedded systems with PCIe x16 slots
• Maintenance scenarios where quick drive replacement is needed

Key specifications

• Form factor: Mobile storage rack for two M.2 NVMe drives
• Supported interface: PCIe 4.0 x16 host connection
• Drive compatibility: Removable M.2 NVMe modules (two slots)
• Primary use: Hot-swappable high-speed storage access

How to use

Install the ToughArmor MB842MP-B into an available PCIe 4.0 x16 slot on a compatible host system following the host platform’s installation procedures. Insert M.2 NVMe drives into the removable carriers and slide the carriers into the rack until they are secured. For drive removal, follow standard hot-swap and operating system guidelines for safe removal or ensure the host system places the drive offline before extracting the carrier. Observe the host system’s requirements for lane allocation and NVMe support.

Recommendations

Ensure the host motherboard or chassis supports NVMe operation over PCIe and that adequate cooling is provided for high-performance M.2 NVMe drives. Follow standard hot-swap practices and back up data before performing drive changes.
