💎 IBM 400GB 12Gb/s Enterprise Performance SAS SSDModels: 00AK371, 00Y5951, 00WY980 | HUSMM1640ASS200 | 12Gb/s SAS

This IBM 400GB SAS SSD is an elite-tier enterprise storage solution designed specifically for the IBM Storwize V5000 Gen2 (V5000 V2) and high-performance System x architectures. Manufactured by HGST (Ultrastar SSD1600MM series), this drive features 24nm Enterprise MLC (eMLC) NAND and a high-speed 12Gb/s SAS interface. It is engineered for "Mainstream Endurance," meaning it is built to handle heavy, continuous write workloads common in mission-critical data centers.

📊 Technical Specifications

• Capacity: 💾 400 GB

• Interface: ⚡ SAS-3 12.0 Gb/s (Dual Port)

• Form Factor: 📏 2.5-inch SFF (Small Form Factor)

• NAND Type: 🧩 Enterprise MLC (eMLC)

• Random Read/Write: ⚡ 130,000 / 100,000 IOPS

• Endurance (DWPD): 🛡️ 10 Drive Writes Per Day (High Endurance)

• MTBF: 🏆 2.5 Million Hours

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally tested and secure-erased to NIST 800-88 standards. Verified for 100% health and peak performance in enterprise storage arrays.

• Mainstream Endurance (10 DWPD): This is a "Performance" grade drive, not a "Value" drive. It can handle up to 4TB of random writes per day, making it perfect for write-intensive database logs and caching tiers.

• 12Gb/s SAS Throughput: Fully optimized for 12G backplanes, providing the massive bandwidth required for high-virtualization densities and real-time analytics.

• Data Protection: Features Power Loss Data Management and T10 End-to-End Data Protection, ensuring your data is never lost or corrupted during unexpected power events.

• IBM Certified Firmware: Comes with genuine IBM/Lenovo firmware to ensure seamless compatibility, thermal reporting, and management within IBM Storwize and System x environments.

📦 Compatibility & Use Case

• Primary Target: Specifically listed for IBM Storwize V5000 (2078-AC94). It is also a drop-in replacement for part numbers 00AK371, 00Y5951, and 00WY980.

• Best For: Tier-0 storage, SQL database indexing, VDI boot storms, and any environment where 24/7 reliability and high IOPS are non-negotiable.
