The **M2AS1-5413-R2** is a high-performance, industrial-grade **M.2 Solid State Drive (SSD)** manufactured by **Innodisk**. It belongs to the M.2 (S42) 3TE7 series, utilizing 3D TLC (Triple-Level Cell) flash memory. Below is a detailed breakdown of its electronic components and technical specifications. --- ## 1. Core Technical Specifications | Feature | Specification | | :--- | :--- | | **Interface** | SATA III 6.0 Gb/s | | **Form Factor** | M.2 2242 (S42) - 22mm x 42mm | | **Flash Type** | 3D TLC (Triple-Level Cell) | | **Capacity Range** | Typically 32GB to 512GB (Model specific) | | **Sequential Read** | Up to 560 MB/s | | **Sequential Write** | Up to 330 MB/s | | **Power Consumption** | Max 2.0W (approx.) | | **MTBF** | >3 million hours | --- ## 2. Key Electronic Components & Technologies ### A. The Controller The heart of the M2AS1-5413-R2 is a sophisticated SATA III controller. It manages data flow between the host system and the NAND flash. It includes: * **Error Correction Code (ECC):** Uses LDPC (Low-Density Parity-Check) to ensure data integrity. * **Wear Leveling:** Sophisticated algorithms that distribute write/erase cycles evenly across the flash blocks to prolong the drive's lifespan. * **Bad Block Management:** Identifies and bypasses failed memory cells. ### B. NAND Flash Memory (3D TLC) Instead of traditional flat (planar) cells, this part uses **3D NAND** technology. * **Vertical Stacking:** Allows for higher density in a small physical footprint (2242 size). * **Reliability:** Provides a better balance between cost, capacity, and endurance compared to standard consumer-grade TLC. ### C. Power Management IC (PMIC) The drive contains integrated circuits designed to manage voltage conversion from the M.2 slot (3.3V) to the internal voltages required by the NAND and Controller. * **iPower Guard:** A specialized technology by Innodisk that protects the SSD during startup and shutdown against unstable power inputs. --- ## 3. Advanced Features for Industrial Use * **iData Guard:** A firmware-based power-loss protection mechanism. It ensures that the last command is completed and data is safely stored during an unexpected power drop. * **Thermal Sensor:** Monitors the temperature of the electronic components. If the drive exceeds safe operating limits (usually 0°C to +70°C for standard or -40°C to +85°C for industrial), it may throttle performance to prevent hardware damage. * **S.M.A.R.T. Monitoring:** Allows the host system to monitor the "health" of the electronic parts, including remaining life percentage and erase counts. --- ## 4. Physical Layout (M.2 2242) The "5413" designation refers to the 2242 form factor, which is smaller than the standard 2280 found in laptops. * **Pin Configuration:** B+M Key (compatible with most M.2 slots that support SATA signals). * **Dimensions:** 22.0mm x 42.0mm x 3.5mm.
