The **M2AS1-A221-R2** is a specific part number typically associated with high-performance **Industrial SSD (Solid State Drive) modules**, specifically following the **M.2 2280** form factor. These are often utilized in embedded systems, servers, and industrial automation due to their durability and power loss protection features. --- ### Technical Specifications Below are the primary electronic and physical specifications for this component: | Feature | Specification | | :--- | :--- | | **Form Factor** | M.2 2280 (80mm length) | | **Interface** | SATA III 6.0 Gbps (Backward compatible) | | **Capacity** | Typically 128GB to 256GB (model variant dependent) | | **Flash Type** | industrial-grade 3D TLC or MLC | | **Operating Voltage** | 3.3V ± 5% | | **Operating Temp** | 0°C to 70°C (Standard) / -40°C to 85°C (Industrial) | --- ### Key Electronic Components The "R2" revision of this module usually indicates a hardware refresh or a specific controller/firmware optimization. The internal architecture consists of: #### 1. The Controller The brain of the SSD. It manages the **ECC (Error Correction Code)**, wear leveling, and bad block management. In industrial models like the M2AS1, the controller is optimized for high IOPS (Input/Output Operations Per Second) and data integrity. #### 2. NAND Flash Memory This is where data is stored non-volatilely. * **3D TLC/MLC:** Uses stacked layers of cells to increase density. * **Endurance:** Designed for high P/E (Program/Erase) cycles compared to consumer-grade drives. #### 3. Power Management IC (PMIC) The circuitry responsible for: * **Voltage Regulation:** Converting the 3.3V input to lower voltages for the controller and NAND. * **Power Loss Protection (PLP):** Often includes tantalium capacitors or "PowerShield" technology to ensure data in the cache is written to the NAND if power is suddenly cut. --- ### Common Applications * **Industrial PCs:** Used as boot drives for automation software. * **Digital Signage:** High reliability for 24/7 continuous operation. * **Medical Equipment:** Requires stable performance and long-term supply availability. * **Networking Gear:** Used in routers and switches for OS storage.
