Raidon Technology Unveils PC05M-42 Dual M.2 NVMe PCIe Expansion Adapter

Raidon Technology, Inc. unveils the PC05M-42 Dual M.2 NVMe PCIe expansion adapter.

The PC05M-42 is a PCIe Gen3 x4 dual-M.2 NVMe expansion adapter built for serviceable, predictable storage growth. An onboard PCIe switch enables 2 independent NVMe SSDs to operate from a single PCIe slot – no motherboard PCIe bifurcation required – with a dedicated PCIe Gen3 x2 link to each SSD for consistent behavior under concurrent workloads.

For fast deployment and minimal downtime, the card uses tool-free, removable SSD trays for quick installation and field replacement. A built-in 40mm active cooling fan helps reduce thermal throttling during sustained operation, and broad M.2 support (2230/2242/2260/2280) keeps sourcing flexible.

Performance note:
Total throughput is ultimately limited by the upstream PCIe Gen3 x4 host link (the 2 SSDs share the x4 uplink under simultaneous load).

Hot-plug / Hot-swap Note: NVMe hot-plug/hot-swap is platform dependent and requires support across PCIe hot-plug topology, BIOS/firmware, and OS configuration. Where supported, the PC05M-42’s tray-based access can reduce service time – but hot-swap should not be assumed on all desktop or server platforms.  

Key Features:

Dedicated Dual-Channel PCIe Performance

• PCIe Gen3 x4 host interface
• x2 + x2 lane allocation to 2 NVMe SSDs
• Consistent throughput under concurrent multi-drive access

Dual M.2 NVMe SSD Support

• Supports 2 NVMe SSDs in a single PCIe slot
• Ideal for capacity expansion, data separation, and JBOD / Independent Mode

Wide M.2 Form-Factor Compatibility

• Supports 2230 / 2242 / 2260 / 2280 M.2 NVMe SSDs
• Flexible SSD sourcing and upgrade planning

Tool-Free, Service-Optimized Design

• Screwless, tool-free SSD installation and removal
• Designed to reduce maintenance time and simplify field replacement
• Hot-swap is supported when the system BIOS/OS supports NVMe hot-plug (BIOS/OS dependent)

Active Cooling for Stable Performance

• Built-in 40 mm (4 cm) cooling fan
• Helps prevent NVMe thermal throttling during long or heavy workloads
• Supports stable operation in continuous-duty scenarios

 Applications:

• High-Performance Workstations: Dual NVMe boosts speed and efficiency for demanding creative workloads
• Enterprise and Server Systems: Expands storage with easy serviceability for data-intensive applications
• Industrial and Embedded Computing: Active cooling ensures stable operation in compact or harsh environments

  
Frequently Asked Questions: 
Q1: What is the difference between PC05M-42 and PC04M-41?
A: PC05M-42 supports 2 NVMe SSDs via an onboard PCIe switch (x2 + x2). PC04M-41 supports one NVMe SSD (x4)
 
Q2: Does each SSD have its own bandwidth?
A: Yes. Each SSD is allocated a PCIe Gen3 x2 link, but both share the upstream Gen3 x4 host link under simultaneous load.
 
Q3: Do I need tools to install or remove SSDs?
A: No - tool-free trays are designed for fast installation and replacement. 
 
Q4: Can I hot-swap SSDs without shutting down?
A: Only if your platform explicitly supports NVMe hot-plug/hot-swap (BIOS/OS + PCIe topology).
 
Q5: What systems is PC05M-42 suitable for?
A: Desktops, workstations, servers, and industrial systems that need service-friendly dual-NVMe expansion.
