💎 IBM 500GB 7.2K SATA 2.5" Enterprise Hard DriveModel: ST9500620NS | IBM PN: 42D0753 | 7,200 RPM | SATA 6Gb/s | 64MB Cache The IBM 42D0753 (Seagate Constellation.2 model ST9500620NS) is a high-performance, small form factor (SFF) drive engineered for 24/7 enterprise reliability. While many 2.5-inch SATA drives are designed for laptops, the Constellation.2 series is built specifically for server and storage arrays. It features a robust 7,200 RPM spindle speed and SATA 6Gb/s interface, offering a compact storage solution for high-density environments where power efficiency and data integrity are critical. 📊 Technical Specifications Capacity: 💾 500 GB Interface: ⚡ SATA 6Gb/s (SATA III) Spindle Speed: 🏎️ 7,200 RPM Cache: 🧠 64 MB Form Factor: 📏 2.5-inch SFF MTBF: 🛡️ 1.4 Million Hours Sector Format: 💾 512n (Native) Recording Technology: 🖋️ CMR (Conventional Magnetic Recording)
✅ Why This Drive Rocks Condition: ✨ Refurbished - Excellent. Professionally audited, secure-erased to NIST 800-88 standards, and verified for 100% health. This drive is optimized for reliability in production server environments. IBM Genuine Firmware: Carries authentic IBM firmware (42D0753), ensuring seamless integration with IBM System x, BladeCenter, and Power Systems. It provides accurate health reporting and LED status indicators within the IBM ecosystem. 512n Native Format: The 512-byte native sector format ensures 100% compatibility with older legacy RAID controllers and operating systems that do not support modern 4K Advanced Format drives. Low Power Consumption: The 2.5-inch design consumes significantly less power and generates less heat than traditional 3.5-inch drives, helping to lower the total cost of ownership (TCO) in large deployments.
📦 Compatibility & Use Case Target Systems: Optimized for IBM System x servers, IBM BladeCenter chassis, and IBM Power Systems. Also compatible with any standard 2.5" SATA bay in Dell, HP, or Supermicro hardware. Ideal Workloads: Entry-level server boot drives, localized caching, small-scale web hosting, and edge computing appliances. Universal Fit: Standard SATA III interface is fully backward compatible with SATA II and SATA I backplanes.
