💎 IBM 4TB 7.2K SAS 12Gb/s Enterprise Hard DriveModel: ST4000NM0043 | IBM PN: 98Y3241 | IBM FRU: 98Y3197 / 00D5320 | 7,200 RPM | SAS 12Gb/s

The IBM 98Y3241 (manufactured by Seagate as the Constellation ES.3 / Enterprise Capacity series) is a high-performance, high-capacity drive built for IBM System x and Storwize storage environments. This model is a significant step up from previous versions as it supports the 12Gb/s SAS interface, providing double the interface bandwidth. Engineered for massive data growth and 24/7 reliability, it is the ideal choice for capacity-optimized enterprise storage.

📊 Technical Specifications

• Capacity: 💾 4 TB

• Interface: ⚡ SAS 12Gb/s (SAS-3 Dual Port)

• Spindle Speed: 🏎️ 7,200 RPM

• Cache: 🧠 128 MB

• Form Factor: 📏 3.5-inch LFF

• MTBF: 🛡️ 1.4 Million Hours

• Sector Format: 💾 512n (Native)

• Recording Technology: 🖋️ CMR (Conventional Magnetic Recording)

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited and health-verified. Every unit undergoes a multi-pass secure erase and a rigorous stress test to ensure it meets original factory mechanical specifications.

• IBM Certified Firmware: This is a genuine IBM-certified part. The internal firmware is specifically coded to communicate with IBM/Lenovo ServeRAID and Storwize V-Series controllers, ensuring full health telemetry and zero "unsupported drive" flags.

• 12Gb/s Speed: While backward compatible with 6Gb/s controllers, this 12Gb/s drive is optimized for modern backplanes, offering faster burst rates and reduced data bottlenecks.

• 128MB Cache: Features an expanded cache for faster command processing and improved performance in random-write heavy workloads.

• Native 512n Format: Native 512-byte sectors ensure 100% "plug-and-play" compatibility with older legacy RAID controllers and operating systems that cannot handle 4K Advanced Format drives.

• Enterprise Durability: Equipped with Rotational Vibration (RV) sensors, allowing it to maintain high performance and accuracy even when packed into high-density storage shelves.

📦 Compatibility & Use Case

• Target Systems: Optimized for IBM System x (x3500, x3550, x3650 M4/M5), Lenovo ThinkSystem, and IBM Storwize V3700 / V5000 arrays.

• Ideal Workloads: Tier-2 storage, big data archiving, high-capacity RAID 6 arrays, and enterprise-grade backup targets.

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