The **M2AS1-4144-R2/CE** is a specialized high-performance computing component, specifically a **M.2 Solid State Drive (SSD)** designed for industrial or embedded applications. This part is part of the Cervoz industrial storage lineup. --- ### 1. General Specifications The device is built to handle intensive data workloads and harsh environmental conditions that standard consumer SSDs cannot tolerate. | Feature | Specification | | :--- | :--- | | **Form Factor** | M.2 2280 (80mm length) | | **Interface** | SATA III 6.0Gb/s | | **NAND Flash Type** | MLC (Multi-Level Cell) | | **Capacity** | 128GB (Standard for this specific part number) | | **Operating Temp** | 0°C ~ 70°C (Standard Grade) | --- ### 2. Key Electronic Components The internal PCB of the M2AS1-4144-R2/CE consists of several critical electronic sub-systems: #### A. NAND Flash Memory * **Technology:** Uses MLC (Multi-Level Cell) chips. * **Function:** This is the non-volatile storage where data is physically kept. MLC provides a balance between the high endurance of SLC and the high density of TLC. #### B. The Controller * **Function:** The "brain" of the SSD. It manages error correction (ECC), wear leveling (distributing writes across the flash to prevent premature failure), and bad block management. * **Protocol:** It translates SATA commands from the host computer into signals the NAND chips understand. #### C. DRAM Cache (Conditional) * Some variants in this family include a DDR3/DDR4 DRAM chip to store the **L2P (Logical-to-Physical) mapping table**. This significantly speeds up small-block random write operations. #### D. Power Management IC (PMIC) * **Voltage Regulation:** Converts the 3.3V supplied by the M.2 slot into lower voltages (typically 1.8V and 1.2V) required by the controller and NAND. * **Protection:** Includes capacitors for noise filtering to ensure stable data transmission. --- ### 3. Industrial Grade Features Unlike consumer parts, the "CE" suffix and "R2" revision often denote specific industrial optimizations: 1. **Fixed BOM:** The internal electronic components (Controller/NAND) are locked. They will not be changed without a formal Product Change Vital (PCN), ensuring long-term compatibility for factory machines. 2. **Shock/Vibration Resistance:** The electronic solder joints are often reinforced to withstand mechanical stress in industrial environments. 3. **Advanced ECC:** Uses sophisticated algorithms to detect and fix bit-flips caused by electronic interference. ---
