Description

IBM 81Y9726 500GB 7.2K NL SATA 6Gb/s 2.5-inch SFF Hot-Swap HDD (Lot of 4): This is a lot of 4 IBM 81Y9726 500 GB nearline (NL) SATA hard drives based on Seagate Constellation.2 ST9500620NS media. Each drive is a 7200 RPM 2.5-inch SFF SATA 6 Gb/s spinning HDD intended for IBM/Lenovo System x and Flex System hot-swap bays. NL SATA in this class targets capacity-tier workloads, not random-IO performance. These are refurbished drives.

Engineering Context

NL SATA (Nearline SATA) drives spin at 7200 RPM and use a 6 Gb/s interface, but with enterprise firmware tuned for 24x7 operation in multi-bay chassis. The 2.5-inch SFF form factor allows higher drive density per RU than 3.5-inch LFF. Rotational latency at 7200 RPM is approximately 4.16 ms, with typical sustained sequential throughput around 100–130 MB/s on this generation. Random IOPS on a single 7200 RPM drive is roughly 75–100 IOPS depending on access pattern; SSDs remain the appropriate choice for transactional workloads.

Deployment & Use Cases

Capacity replacement drives in IBM System x x3550 M4, x3650 M4, and Flex System x240/x440 nodes. Backup repository spindles for ProtecTIER, Veeam, and Spectrum Protect on IBM hardware. Cold storage tiers in software-defined storage where 2.5-inch SFF density is preferred over 3.5-inch LFF.
