WD Blue 4TB desktop drive for everyday computing
This 3.5 inch internal hard drive is built for daily office and web workloads. It fits standard desktop bays and connects through a SATA 6.0Gb/s interface. The 4TB capacity suits primary storage in home or office PCs.
SMR recording technology shapes write behaviour
The drive uses Shingled Magnetic Recording to reach 4TB at this price point. Sequential reads run at 5400 RPM with 256MB cache, while sustained random writes slow once the cache fills. Buyers needing consistent write throughput for databases or video capture should consider a CMR alternative.
Four terabytes hold large media libraries
The 4TB volume comfortably stores photo collections, documents and local backups with room to spare. Performance drops when the drive is pushed past its cache buffer during heavy multi-tasking or large-file shuffling. It is not suited for high-write NAS arrays or constant surveillance recording.

Questions about this item
How does the 5400 RPM spindle speed affect everyday desktop performance?
The 5400 RPM rotation provides reliable throughput for office tasks, web browsing and bulk file storage, while keeping power draw and noise lower than faster desktop drives.
What does the SATA 6.0Gb/s interface limit in actual use?
The SATA 6.0Gb/s link caps the maximum burst transfer at 6.0Gb/s; sustained read and write speeds will be lower and are governed by the drive's 5400 RPM mechanics and 256MB cache.
Will the 26.10mm height fit a standard 3.5-inch drive bay?
Yes, the 26.10mm height matches the standard 3.5-inch form factor, so it mounts in any desktop bay or tray designed for 3.5-inch drives.
