About This Product
Overview
The HGST Ultrastar HUS724040ALS640 is an enterprise-class 4TB HDD designed for use in compatible server environments. Built in a 3.5-inch LFF form factor, it offers a practical storage option for systems that rely on SAS connectivity and standard large-form-factor drive bays. As part of the Ultrastar Enterprise Series, this drive is intended for business and data center applications where consistent storage access and broad server compatibility are important. Its 12Gb/s SAS interface makes it suitable for enterprise platforms that support this connection type, while the 7200 RPM spindle speed provides a familiar balance of capacity and performance for general-purpose server storage. For IT teams looking to expand or replace storage in supported systems, this HGST drive offers a straightforward enterprise HDD option with a proven design approach.
Performance & Scalability
With a 7200 RPM spindle speed and SAS interface, this drive is well suited for workloads that need reliable mechanical storage in server deployments. It can be used for capacity expansion, replacement of existing drives, or as part of a larger storage pool in an enterprise environment. The 12Gb/s SAS interface supports integration into compatible systems that are built around SAS backplanes and controllers, helping maintain efficient connectivity within the storage stack. Because it is a 3.5-inch enterprise HDD, it fits into many server chassis that support LFF drives, making it a practical choice for administrators managing mixed storage needs. The hot plug drive support also adds flexibility in supported systems, allowing drives to be serviced more easily when hardware maintenance or upgrades are required.
Storage Flexibility
The 4TB capacity provides a useful amount of storage for file services, backups, archival data, and other enterprise workloads that benefit from dependable HDD capacity. Its 3.5-inch LFF design makes it suitable for systems that prioritize larger drive bays and straightforward installation in compatible server hardware. Because this model is part of the Ultrastar Enterprise Series, it is positioned for environments where storage components need to integrate cleanly with existing infrastructure. The SAS interface is especially valuable in enterprise setups that already use SAS controllers or backplanes, helping simplify deployment across supported platforms. Whether used as a replacement drive or as part of a storage expansion project, this HDD offers a flexible option for organizations that need capacity in a server-ready format.
