The **M2SES2-64-R2/Q** is a high-performance SSD (Solid State Drive) module typically used in industrial, aerospace, or defense applications. It is part of Apacer’s **M.2 2280 SES2 (Signaling Enclosure Services)** series, designed for rugged environments. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Form Factor** | M.2 2280-D2-B-M (80mm x 22mm) | | **Interface** | SATA III 6.0 Gbps | | **Capacity** | 64 GB | | **NAND Flash Type** | SLC-liteX (High Endurance) | | **Security Features** | AES 256-bit Encryption, TCG Opal 2.0 | | **Ruggedization** | MIL-STD-810G Compliant | --- ### 2. Electronic Architecture & Components The "Electronic Parts" of this module are engineered for data integrity and power stability: #### A. The Controller The heart of the SSD is a specialized flash controller that handles: * **LDPC ECC:** Low-Density Parity-Check Error Correction Code to ensure data reliability over time. * **Wear Leveling:** Global wear leveling algorithms to distribute write/erase cycles evenly across the NAND cells. * **SMART Technology:** Monitoring system for reliability analysis. #### B. NAND Flash (SLC-liteX) Unlike standard consumer drives (TLC/QLC), this part utilizes **SLC-liteX** technology. * **Logic:** It mimics Single-Level Cell (SLC) behavior using Multi-Level Cell hardware. * **Benefit:** It significantly increases P/E (Program/Erase) cycles, often reaching up to 100,000 cycles, making it ideal for write-intensive industrial tasks. #### C. Power Management (DataDefender™) The electronic circuit includes high-quality capacitors and a power detector circuit. * **Power Loss Protection:** If the system loses power, the hardware triggers a "flush" command to move data from the volatile DRAM cache/controller buffer into the non-volatile NAND before the capacitors discharge. #### D. Physical Build * **Gold Fingers:** 30μ gold plating on the connector to prevent oxidation and ensure stable signaling in humid or vibrating environments. * **Thermal Sensor:** Integrated sensor to throttle performance if temperatures exceed the industrial range (-40°C to +85°C). --- ### 3. "SES2" Special Functionality The **SES2** designation refers to specific electronic signaling for enclosure management. It allows the host system to monitor the status of the drive (such as temperature, health, and power status) through out-of-band signaling, which is critical for mission-critical server or storage arrays. ---
