Lenovo 4XB7A83351 20TB 7.2K SAS 3.5 in HDD | Enterprise Storage

Scale storage capacity without changing the architecture of your server environment. This Lenovo 20 TB enterprise hard drive pairs a 7.2K RPM spindle with a SAS interface to deliver large-volume storage for workloads that value capacity, compatibility, and predictable operation over flash pricing. The 3.5 in DDIC form factor is suited to server platforms that need dense, high-capacity drive bays for backup repositories, archive tiers, and data sets that are accessed regularly but do not require SSD economics. In those roles, the drive gives infrastructure teams a straightforward way to expand usable storage while staying within established Lenovo server configurations. For procurement teams, the Lenovo part number helps maintain platform alignment and simplifies replacement planning across standardized fleets. For operations teams, the SAS interface supports enterprise backplane integration, and the 7.2K RPM class keeps power and cost in check for capacity-oriented deployments. It is a practical choice when the job is to hold more data, reliably, inside the server you already run.
