✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited, health-verified, and 100% surface tested. Each unit has been cleared of all data and verified for mechanical stability, ensuring it is ready for high-uptime Cisco environments.

• Cisco Certified Firmware: This drive features genuine Cisco firmware, ensuring full compatibility with Cisco UCS Manager and Intersight. It provides accurate health telemetry and avoids "unsupported drive" flags in the UCS CIMC.

• Native 512n Sector Format: The 512-byte native format is a significant selling point for administrators maintaining legacy RAID configurations or older OS environments that do not support modern 512e or 4Kn drives.

• Persistent Write Cache (PWC): Includes Toshiba’s PWC technology, which helps protect against data loss during sudden power failures, enhancing data integrity in critical server roles.

• Dual-Port SAS: Features two independent data paths for high availability and failover support, a standard requirement for enterprise-grade server infrastructure.

📦 Compatibility & Use Case

• Target Systems: Optimized for Cisco UCS B200, C460, and C220/C240 M4 and M5 series servers.

• Ideal Workloads: Mid-tier databases, high-performance web servers, virtual desktop infrastructure (VDI), and mission-critical OS boot volumes.

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