The part number **M2AS1-A242-R2/Q** refers to a high-performance **Solid State Drive (SSD)** manufactured by **Innodisk**. It belongs to their M.2 (S42) flash storage series, typically utilized in industrial, embedded, and aerospace applications due to its ruggedized design. --- ### Technical Specifications The breakdown of its electronic and physical characteristics is as follows: | Feature | Specification | | :--- | :--- | | **Form Factor** | M.2 2242 (S42) | | **Interface** | SATA III 6.0 Gb/s | | **Flash Type** | iSLC (Industrial SLC-like technology) | | **Capacity** | 242GB (approx.) | | **Dimensions** | 22.0mm x 42.0mm x 3.5mm | | **Operational Temp** | Standard (0°C ~ +70°C) or Wide Temp (-40°C ~ +85°C) depending on specific suffix | | **Security Features** | iData Guard, iCell, iPower Guard | --- ### Key Electronic Components The drive's performance and reliability are driven by several critical onboard electronic systems: #### 1. NAND Flash Controller The "brain" of the SSD. It manages data placement, Wear Leveling, and Error Correction Code (ECC). In this specific model, the controller is optimized for **iSLC technology**, which offers significantly higher endurance (up to 30,000 P/E cycles) compared to standard MLC or TLC flash. #### 2. iData Guard & iPower Guard These are hardware-integrated power management circuits. * **iPower Guard:** Acts as a protection circuit that prevents data instability during power-up and power-down. * **iCell Technology:** Often includes a bank of tantalum capacitors (surface-mounted) that provide "hold-up" energy, allowing the drive to flush cached data to the NAND flash if the host loses power suddenly. #### 3. SATA III PHY (Physical Layer) The electronic interface that handles the high-speed differential signaling between the host computer and the SSD controller, ensuring data integrity across the 6Gb/s bus. #### 4. Thermal Sensor An onboard integrated circuit (IC) that monitors the temperature of the controller and flash chips. If the drive exceeds safety thresholds, the firmware can initiate "Thermal Throttling" to reduce speed and prevent electronic damage. --- ### Usage Environment Due to the **M.2 2242** size (shorter than standard laptop SSDs), this part is commonly used in: * Fanless Industrial PCs (IPC). * Automation controllers (PLCs). * Handheld medical devices. * Embedded networking equipment.
