💎 NetApp / IBM 300GB 15K SAS Enterprise Hard DriveModel: HUS154530VLS300 | NetApp PN: 108-00166 | IBM PN: 95P5066 / 95P4255 | 15,000 RPM | SAS 3Gb/s

The NetApp 108-00166 (manufactured by Hitachi as the Ultrastar 15K450) is a high-performance, mission-critical drive designed for high-availability enterprise storage arrays. Built with a 15,000 RPM spindle speed and a SAS 3Gb/s interface, this drive is engineered for the low-latency demands of Tier-1 storage. While it bears an IBM/NetApp part number, it is the industry-standard Hitachi 15K450 platform known for exceptional mechanical durability.

📊 Technical Specifications

• Capacity: 💾 300 GB

• Interface: ⚡ SAS 3Gb/s (Dual Port)

• Spindle Speed: 🏎️ 15,000 RPM

• Cache: 🧠 16 MB

• Form Factor: 📏 3.5-inch LFF

• Sector Format: 💾 520bps (NetApp/IBM Native)

• Recording Technology: 🖋️ CMR (Conventional Magnetic Recording)

• Average Seek Time: ⏳ 3.4 ms

✅ Why This Drive Rocks

• Condition: ✨ Refurbished - Excellent. Professionally audited, secure-erased, and health-verified. These units are tested for stable 15K RPM operation, ensuring the fluid dynamic bearings are quiet and perform to original specs.

• Specialized 520-Byte Formatting: This drive is pre-formatted to 520-byte sectors, which is mandatory for NetApp FAS systems and certain IBM TotalStorage/DS arrays. It will work out of the box where standard 512-byte drives would fail.

• Dual-Port SAS Reliability: Native dual-porting ensures redundant data paths, a requirement for enterprise-grade high availability (HA) configurations.

• Hitachi Engineering: The Ultrastar 15K450 series is famous for its Rotational Vibration Safeguard (RVS), maintaining peak performance even in dense, multi-drive storage shelves.

📦 Compatibility & Use Case

• Target Systems: Optimized for NetApp FAS series (FAS2040, FAS3140, etc.) and IBM System Storage (DS3200, DS3400). Compatible with NetApp DS14mk2 SAS disk shelves.

• Ideal Workloads: Transactional databases, OS boot volumes for legacy enterprise servers, and localized high-performance caching.

• Firmware Note: Carries specific NetApp/IBM firmware. While it can be reformatted to 512-byte for standard server use, its primary value is as a specialized replacement part for NetApp/IBM storage.
