✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited, health-verified, and 100% surface tested. These drives are verified for mechanical precision to ensure they meet the rigorous uptime standards of a Cisco UCS environment.

• Cisco UCS Certified: Carrying the official Cisco firmware, this drive is guaranteed to be recognized by Cisco UCS Manager and Intersight. It provides seamless integration and full health telemetry, avoiding the "unsupported drive" flags often seen with generic hardware.

• Maximum Mechanical Performance: The 15,000 RPM motor delivers the lowest possible latency for a mechanical drive, making it significantly more responsive than 10K drives for random read/write tasks.

• 12Gb/s SAS Interface: Provides massive data throughput, ensuring that the interface is never the bottleneck in your high-speed server configuration.

• Native 512n Formatting: Uses the 512-byte native sector format, ensuring 100% compatibility with older RAID controllers and legacy OS environments that do not support modern "Advanced Format" (512e/4Kn) drives.

📦 Compatibility & Use Case

• Target Systems: Optimized for Cisco UCS B-Series Blade Servers and C-Series Rack Servers (e.g., C220 M4/M5, C240 M4/M5, B200 M4/M5).

• Ideal Workloads: Mission-critical OS boot volumes, high-frequency transactional databases, intensive logging, and VDI (Virtual Desktop Infrastructure) performance tiers.

• Controller Note: ⚠️ Important: This is a SAS drive. It requires a SAS-capable backplane and controller. It will not function in a standard consumer SATA laptop or desktop port.
