The Lenovo Storage 20TB 7.2K RPM NL-SAS LFF HDD is a high-capacity hard disk drive designed to deliver reliable and scalable storage in enterprise storage systems. With an impressive 20TB capacity, this HDD operates at a rotational speed of 7,200 RPM, ensuring an optimal balance between performance, capacity, and energy efficiency. It utilizes the Near-Line Serial Attached SCSI (NL-SAS) interface, which combines the reliability of SAS with the economics of SATA, making it perfect for applications that require high-volume storage, such as backups, data archiving, big data, and hybrid cloud environments.

This module comes complete with the carrier (mounting bracket) required for direct installation into the enclosure, plus front LEDs for monitoring drive status. These LEDs indicate conditions such as activity, failure, or health status, making them easier to maintain in data center environments. The 3.5-inch (LFF – Large Form Factor) form factor is ideal for enclosures that support larger drives, maximizing storage density without compromising performance.
