The **M2PRU-C7M-R** is a specific model within the **ORICO** series of portable NVMe M.2 SSD enclosures. It is designed to bridge the gap between high-speed internal storage and external connectivity. --- ### 1. Technical Specifications The device acts as a hardware bridge, converting the PCIe signal of an SSD into a USB signal. | Feature | Specification | | :--- | :--- | | **Interface Protocol** | NVMe (PCIe Gen3 x4) | | **Output Port** | USB 3.1 Gen2 Type-C | | **Transfer Speed** | Up to 10Gbps | | **Controller Chip** | Realtek RTL9210 | | **Supported Sizes** | 2230, 2242, 2260, 2280 | | **Material** | Aluminum Alloy + ABS Plastic | --- ### 2. Key Electronic Components The "Electronic Parts" of this device revolve around its Printed Circuit Board (PCB) and the integrated circuits that manage data flow: #### A. The Bridge Controller (Realtek RTL9210) The heart of the M2PRU-C7M-R is the **Realtek RTL9210** bridge chip. - **Function:** It translates the NVMe (PCIe) language into USB 3.1 Gen2 language. - **Power Management:** It features low power consumption and supports the **UASP** (USB Attached SCSI Protocol) and **TRIM** commands, which are essential for maintaining SSD health and speed. #### B. Thermal Management System Because NVMe SSDs generate significant heat during high-speed transfers, the electronics are paired with: - **Thermal Pads:** To conduct heat from the chips to the casing. - **Fin-style Heat Sink:** The "C7M" variant often features a finned aluminum design to increase surface area for passive cooling. #### C. Power Delivery Circuitry The PCB contains voltage regulators that convert the 5V supplied by the USB port into the 3.3V required by the NVMe SSD. It includes: - **Capacitors:** To stabilize voltage and prevent data corruption during minor power fluctuations. - **Circuit Protection:** Over-current and short-circuit protection to safeguard the connected SSD. --- ### 3. Usage & Compatibility - **Compatible SSDs:** Only M-Key or B+M Key NVMe PCIe SSDs. It is **not** compatible with older B-Key SATA M.2 drives. - **Operating Systems:** Driver-free (Plug and Play) for Windows, macOS, and Linux. ```json { "device_type": "SSD Enclosure", "max_bandwidth": "1250 MB/s", "connector": "USB-C" } ```
