Lenovo 4XB7A09100 12TB 7.2K NL-SAS 3.5" HDD | Enterprise Storage

Increase usable storage density with this Lenovo 12 TB 3.5-inch NL-SAS hard drive. The 7,200 RPM spindle speed gives you the familiar behavior of enterprise nearline disk, while the SAS-based interface supports deployment in systems designed for high-capacity, serviceable storage tiers. This drive is a practical fit for environments that need to store more data per bay without moving to a more expensive flash tier. It is well suited to backup repositories, reference data, media libraries, and general capacity expansion in Lenovo infrastructure. The 3.5-inch form factor makes it easy to slot into established server and storage chassis, while the nearline design keeps the focus on density and lifecycle economics. For procurement teams, this model is about reducing complexity at scale. A validated Lenovo part number helps standardize spares, simplify qualification, and keep replacement planning predictable. For infrastructure teams, it offers the kind of capacity headroom that matters when growth is steady and downtime is not an option.
