Western Digital WDS400T1R0A Red 4TB 2.5 Inch Nas Ssd

Product Description

The Western Digital WDS400T1R0A is a 2.5-inch SATA solid-state drive from the WD Red product line, designed for use in network-attached storage systems and always-on NAS enclosures. With a 4TB capacity, this drive is built to handle the sustained read and write demands of multi-bay NAS environments where drives run continuously. NAS integrators, IT technicians, and storage professionals install this drive as a primary or replacement storage unit in compatible NAS enclosures.

This drive is suited for small business and home office NAS deployments where high-capacity, reliable solid-state storage is required. The 2.5-inch form factor fits standard NAS bays that accept 2.5-inch SATA drives. It is a direct-install option for builds requiring SSD-class performance in a NAS chassis, including surveillance storage arrays and file-server applications where spinning-disk noise and vibration are concerns.
