As part of the MG03 business-critical series, this drive provides the reliability of the SAS interface, offering dual-port redundancy and superior error recovery compared to standard SATA drives. With a massive 4TB capacity, it is an ideal solution for scaling out storage in mid-tier servers and high-density disk shelves.

📊 Technical Specifications

• Capacity: 💾 4 TB

• Interface: ⚡ SAS 6Gb/s (Dual Port)

• Spindle Speed: 🏎️ 7,200 RPM

• Cache: 🧠 64 MB

• Form Factor: 📏 3.5-inch LFF

• MTBF: 🛡️ 1.2 Million Hours

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited and health-verified. Each drive undergoes a rigorous diagnostic process, including full surface scans and secure erasure, to ensure "as-new" performance.

• Dual-Port SAS Reliability: The SAS interface allows for two independent data paths, ensuring that the drive remains accessible even if a controller or cable fails—a critical feature for mission-critical enterprise storage.

• Native 512n Formatting: This drive utilizes 512-byte native sectors, making it exceptionally compatible with older RAID controllers and legacy server operating systems that do not support modern "Advanced Format" (512e/4Kn) drives.

• Built for Multi-Drive Bays: Features advanced vibration compensation technology, allowing it to maintain high performance and data accuracy even when installed in large 12-bay or 24-bay storage enclosures.

• Persistent Write Cache (PWC): Toshiba’s specialized caching technology helps protect data integrity during unexpected power loss, making it a safer choice for complex RAID rebuilds.

📦 Compatibility & Use Case

• Target Systems: Perfect for Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro servers equipped with a SAS backplane/controller.

• Ideal Workloads: Tier-2 enterprise storage, high-capacity RAID arrays (RAID 5/6/10), large-scale file servers, and backup repositories.

• Controller Requirement: ⚠️ Note: This is a SAS drive. It requires a dedicated SAS controller (HBA or RAID card) and will not work if plugged into a standard desktop SATA port.
