The WD Blue WD40EZAZ is a 3.5-inch internal hard drive that offers 4 TB of storage capacity, intended for use in desktop computer systems. It is engineered for consistent operation in standard office and web-based applications. The drive integrates NoTouch Ramp Load technology, which parks the recording head safely off the disk surface to protect data and reduce wear when the drive is not active. This model has undergone comprehensive compatibility testing to ensure functionality across a variety of PC builds and enclosures.

Connection to the motherboard is established through a SATA III interface, which provides a data transfer rate of up to 6 Gbit/s. The drive's internal mechanics feature a 5400 RPM spindle speed and a 256 MB buffer, which work together to handle read and write requests for typical desktop tasks. This HDD is also equipped with S.M.A.R.T. capabilities, allowing the system to monitor drive health and anticipate potential issues. The 5.56 ms average latency contributes to its responsiveness during file access operations.
