Lenovo Seagate 16 TB NL-SAS HDD 4XB7A99931 | 3.5 in, Enterprise

Build out capacity without overpaying for flash where it is not required. This Lenovo Seagate 16 TB NL-SAS hard drive is aimed at storage tiers that prioritize density, economics, and dependable access for large datasets. In enterprise arrays, nearline SAS gives you a practical balance between SATA-class capacity and the management characteristics expected in server storage environments. The 3.5-inch form factor makes it suitable for high-capacity bays in supported Lenovo systems, including DSSG configurations. At 16 TB, it is well positioned for backup repositories, archive pools, surveillance retention, and file storage where throughput and capacity matter more than sub-millisecond latency. For infrastructure teams standardizing on Lenovo platforms, this drive offers a straightforward way to expand storage shelves with a familiar enterprise class and a capacity point that reduces drive count per usable petabyte. That means fewer bays consumed, simpler planning, and a storage layer that scales cleanly in capacity-driven deployments.
