Lenovo 00MM730 System X 4TB 3.5" 7.200RPM SAS Internal HDD

The Lenovo 00MM730 is an internal hard disk drive that delivers 4 TB of nearline storage for Lenovo System x servers and other systems that accept a 3.5 inch bay. Built around a spindle that spins at 7,200 RPM and a SAS 3 interface, it balances generous capacity with rotational performance suited to everyday enterprise workloads.

With 64 MB of on-board cache, the drive handles bursts of random access more smoothly than models that rely solely on spindle speed. Administrators who manage file servers, backup targets, or archival repositories can use this capacity to consolidate data without sacrificing the familiarity and straightforward maintenance of spinning media.

The SAS 3 connection lets the drive integrate into existing NL-SAS backplanes, including Lenovo S2200 enclosures that use the large form factor. Once installed, it becomes part of a scalable pool that supports RAID configurations, tiered storage strategies, or simple capacity expansion in mixed-use environments.

Because the drive ships as a bare unit, it fits naturally into upgrade paths where a technician adds individual drives to reach new capacity goals. Data centers, departmental servers, and test labs that need reliable bulk storage for logs, virtual machine images, or large datasets will find it a practical and cost-effective option.
