WD Black 4TB desktop drive

The WD Black WD4005FZBX is a 4TB 3.5-inch internal hard drive built for desktop PCs that need high-capacity storage with responsive performance. It targets creative professionals, gamers and system builders who work with large media libraries or game installations and want a drive that can sustain heavy workloads.

SATA 6.0Gb/s interface with CMR recording

The drive connects through a SATA 6.0Gb/s interface and uses conventional magnetic recording (CMR) technology, which maintains consistent write speeds without the performance dips associated with shingled recording. This specification is the primary factor for buyers who need reliable sustained throughput for video editing, rendering or large file transfers.

Standard 3.5-inch bay installation

The unit fits a standard 3.5-inch drive bay with maximum dimensions of 147.00mm length, 101.60mm width and 26.10mm height, and it ships as a bare drive without cables or mounting brackets. Installation is straightforward for anyone familiar with desktop assembly; the most common issue is forgetting to connect both the SATA data and power cables or leaving the drive unsecured in the bay, which can cause vibration noise.

商品問答

How does the 7200 RPM spindle speed affect real-world load times?

The 7200 RPM rotation reduces rotational latency compared to slower drives, so large game levels, video projectiles and photo libraries open noticeably faster on this 4 TB model.

What does the SATA 6.0Gb/s interface limit in daily use?

The SATA 6.0Gb/s link sets the maximum data rate between the drive and the motherboard, so sustained transfers cannot exceed the bus ceiling even though the 256 MB cache absorbs bursts.

Will the 3.5-inch form factor fit my case’s drive bay?

The drive measures 147.00 mm long, 101.60 mm wide and 26.10 mm high, matching the standard 3.5-inch desktop bay and screw-hole pattern used in most tower cases.
