Dell 500GB 7.2K RPM SAS 6Gb/s Enterprise Hard DriveModel: ST9500430SS | Dell PN: K831N (0K831N) | 500GB Capacity | 7,200 RPM | 6Gb/s SAS

The Dell K831N (manufactured by Seagate as the Constellation.2) is a high-capacity nearline SAS drive designed for enterprise environments that require a balance of storage density and the reliability of a SAS interface. While it operates at 7,200 RPM, it utilizes the 6Gb/s SAS protocol, making it much more robust for multi-drive server configurations than standard SATA drives. It is an ideal choice for high-capacity storage in a small 2.5-inch form factor.

📊 Technical Specifications

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited and health-verified. Each unit undergoes a comprehensive surface scan and mechanical diagnostic to ensure it meets original factory standards for data integrity.

• Enterprise SAS Features: Unlike SATA drives, this SAS model supports Dual-Port connectivity for redundant data paths and advanced error recovery, ensuring your data remains accessible even in complex server environments.

• Genuine Dell Firmware: Pre-loaded with Dell-certified firmware (K831N), ensuring 100% "plug-and-play" compatibility with Dell PERC RAID controllers. It provides full health telemetry to iDRAC and OpenManage without "non-certified" drive flags.

• High-Density Storage: Perfect for populating servers with many 2.5" bays where you need more capacity than high-speed 10K/15K drives typically offer, but still require the stability of the SAS protocol.

• Native 512n Format: The 512-byte native sector format ensures total compatibility with older RAID controllers and legacy operating systems that do not support modern 512e or 4Kn "Advanced Format" drives.

📦 Compatibility & Use Case

• Target Systems: Optimized for Dell PowerEdge Gen 11, 12, and 13 servers (e.g., R610, R710, R620, R720, R630, R730) and PowerVault storage arrays.

• Ideal Workloads: Bulk data storage, tiered storage (Capacity Tier), backup targets, and low-intensity application hosting.

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