Dell 8TB 7.2K SAS 12Gb/s Enterprise Hard DriveModel: HUH721008AL5200 | Dell PN: KRDKK | HGST PN: 0F27399 | 7,200 RPM | 12Gb/s SAS

The Dell KRDKK (manufactured by HGST as part of the award-winning Ultrastar He10 series) is a high-performance, helium-filled enterprise drive. By using HelioSeal® technology, this drive reduces internal turbulence and friction, allowing for a cooler-running, more power-efficient 8TB solution than traditional air-filled drives. Built for the rigorous demands of Dell PowerEdge and PowerVault systems, it offers a high-bandwidth 12Gb/s SAS interface and a massive 256MB cache for superior data throughput.

📊 Technical Specifications

• Capacity: 💾 8 TB

• Interface: ⚡ SAS 12Gb/s (Dual Port)

• Spindle Speed: 🏎️ 7,200 RPM

• Cache: 🧠 256 MB

• Form Factor: 📏 3.5-inch LFF

• MTBF: 🛡️ 2.5 Million Hours

• Sector Format: 💾 512e (Advanced Format)

• Recording Technology: 🖋️ CMR (Conventional Magnetic Recording)

• Design: 🎈 HelioSeal® (Helium-filled)

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited and health-verified. Every unit undergoes a rigorous diagnostic pass, including helium integrity checks and full surface scans to ensure it meets original factory specifications.

• Genuine Dell Firmware: Pre-loaded with Dell-certified firmware, ensuring 100% "plug-and-play" compatibility with Dell PowerEdge servers. It provides full health telemetry to iDRAC and OpenManage without "Non-Certified" drive errors.

• Superior Power Efficiency: The helium-filled design reduces the motor's power draw, leading to a significantly lower Total Cost of Ownership (TCO) in high-density data centers.

• Exceptional Reliability: Boasting a 2.5 Million Hour MTBF, this drive is engineered for 24/7/365 mission-critical availability in the most demanding environments.

• Consistent Performance: As a CMR drive, it offers steady and predictable write speeds, making it ideal for maintaining RAID stability and ensuring fast array rebuilds.

📦 Compatibility & Use Case

• Target Systems: Optimized for Dell PowerEdge Gen 13 and Gen 14 servers (R730, R740, T630, etc.) and Dell PowerVault MD/ME series storage.

• Ideal Workloads: Big Data analytics, centralized file storage, massive RAID 6 arrays, and enterprise-grade backup repositories.

• Note: This is a SAS drive. It requires a SAS-capable backplane and controller. It will not work in a standard consumer SATA desktop motherboard.
