Lenovo 4XB7A99218 24TB NL-SAS 7,200 RPM | 3.5 in, Enterprise

Reduce drive count without sacrificing enterprise storage discipline. The Lenovo 4XB7A99218 pairs 24 TB of nearline SAS capacity with a 7,200 RPM spindle speed, giving infrastructure teams a high-density option for bulk data, backup repositories, and capacity-focused arrays. Its 3.5-inch form factor fits standard enterprise bays and supports the economics of scaling storage where every slot matters. This drive is positioned for Lenovo DSSG environments and other systems that call for large-capacity HDDs rather than performance SSDs. NL-SAS provides the SAS-class connectivity expected in managed storage platforms, while the 24 TB capacity helps reduce rack footprint, cabling complexity, and the operational overhead of managing more, smaller drives. For teams planning around retention, archive growth, or secondary storage tiers, that translates into fewer replacements and cleaner expansion planning. Choose this model when capacity density and platform compatibility carry more weight than raw IOPS. It is a practical fit for enterprise arrays that need dependable spinning media at scale, especially where procurement wants a Lenovo-qualified part number tied to a specific deployment line.
