Lenovo 146GB 10,000 RPM SAS 6Gb/s Enterprise Hard Drive

Model: ST973452SS | Lenovo PNs: 42D0673, 42D0672 | IBM FRU: 42D0673 | 146GB Capacity | 10K RPM

The Lenovo 42D0673 (built on the Seagate Savvio 10K.3 platform) is a high-performance 2.5-inch SAS drive specifically tailored for the IBM System x and Lenovo ThinkServer era. While 146GB is considered a "boutique" capacity today, this drive was a mission-critical staple for high-speed OS boot volumes and localized RAID mirrors. Its 10,000 RPM spindle speed provides the low-latency response times necessary for enterprise computing, while its 6Gb/s SAS interface ensures it integrates smoothly into more modern server backplanes.

✅ Product Overview

• IBM/Lenovo System x Optimization: Features certified firmware to ensure 100% compatibility with ServeRAID controllers (such as the M5014, M5015, and M5110). This ensures accurate "Predictive Failure Analysis" (PFA) and full support within Lenovo XClarity or IBM Director.

• Savvio 10K.3 Reliability: Built on one of Seagate’s most stable SFF platforms, designed for 24/7/365 operation in high-density server racks with a focus on mechanical durability and low power consumption.

• Compact Performance: The 2.5-inch Small Form Factor (SFF) allows for greater airflow and drive density compared to traditional 3.5-inch drives, helping to keep server temperatures lower while maintaining high IOPS.

• Dual-Port SAS Architecture: Provides redundant data paths to the drive, essential for enterprise-class high availability, ensuring that the system remains online even if a single path or controller fails.

📦 Compatibility & Use Case

• Target Systems: Optimized for IBM System x (x3550 M2/M3, x3650 M2/M3), BladeCenter HS22, and early Lenovo ThinkServer rack systems.

• Ideal Workloads: Dedicated operating system boot drives, maintenance of existing RAID-1 or RAID-10 arrays, and localized high-speed application swap space.
