The **M2SES-2BC-R2/Q** is a high-performance, industrial-grade storage module, specifically an **M.2 SATA SSD** (Solid State Drive) designed by **Innodisk**. It belongs to the 3TG6-P series, tailored for embedded systems, automation, and mission-critical applications. --- ### 1. Technical Specifications The following table highlights the core electronic and physical components of this specific part: | Feature | Specification | | :--- | :--- | | **Form Factor** | M.2 (SATA) 2280 | | **Interface** | SATA III (6.0 Gb/s) | | **Flash Type** | 3D TLC (Triple-Level Cell) | | **Capacity** | 256GB (Commonly denoted by the '2B' code) | | **NAND Type** | Industrial Grade 3D NAND | | **DRAM Buffer** | DRAM-less Design (typically) | | **Input Voltage** | +3.3V ± 5% | --- ### 2. Key Electronic Components & Technologies #### A. Controller and Firmware The module uses a specialized SATA controller optimized for industrial workloads. Key firmware features include: * **iData Guard:** A proprietary power-fail management system that protects data during sudden power loss. * **LDPC ECC:** Low-Density Parity-Check Error Correction Code to ensure data integrity over the life of the flash. * **Wear Leveling:** Algorithms that distribute write/erase cycles evenly across the NAND cells to prevent premature failure. #### B. The Flash Storage (3D TLC) Unlike consumer drives, the "Q" or industrial designation often implies a higher grade of 3D TLC NAND. * **P/E Cycles:** Rated for higher Program/Erase cycles than standard consumer SSDs. * **Density:** The 3D stacking allows for high capacity in a small M.2 footprint. #### C. Thermal Management Industrial modules like this are designed with internal thermal sensors. If the drive exceeds its operating temperature (typically 0°C to +70°C for standard, or -40°C to +85°C for wide-temp versions), the controller will engage **Thermal Throttling** to prevent electronic damage. --- ### 3. Pinout Structure (M.2 B+M Key) The M2SES-2BC-R2/Q uses a standard M.2 edge connector. Below is a simplified representation of the signal categories: | Pin Group | Function | | :--- | :--- | | **Power** | 3.3V supply pins for the controller and NAND. | | **SATA Differential Pairs** | High-speed transmit (TX+/-) and receive (RX+/-) lines. | | **Ground (GND)** | Reference voltage and shielding. | | **Control Signals** | DAS/DSS (Device Activity Signal) for LED indicators. | --- ### 4. Part Number Breakdown (Partial) * **M2S:** M.2 SATA Product Line. * **ES:** Industrial 3TG6-P Series. * **2B:** Denotes capacity (256GB). * **C:** Commercial Temperature range (0°C ~ +70°C). * **R2/Q:** Hardware revision and specific firmware/package variants. ---
