WD Blue 4TB

The WD Blue 4TB hard disk ranks among the classic internal HDDs for households and casual users. 3.5" HDDs are designed primarily for data centres and desktop PCs. One of the crucial parameters is obviously the rotational speed (RPM). The 5400 RPM RPM should meet the needs of any casual user. The hard disk provides a storage capacity of 4000 GB. The drive uses a 256 MB memory cache. You can link the Western Digital hard disk and other hardware is facilitated via the SATA III interface.

  • Read speed up to 180 MB/s and write speed up to 180 MB/s
  • 256 MB memory cache
  • Western Digital 3.5" disk is compatible with classic bays
  • Typically, the power consumption of the hard drive is 4,8 W, while in stand-by mode it holds at 0.6 W
  • It communicates with a PC or other devices via the SATA III interface
  • Platter-based hard drives are more susceptible to physical damage, but they offer a great storage capacity/performance ratio

Other Hard Disk Features

Platter hard disks have a notably special construction. The enclosure conceals a mechanism with moving platters, complete with disk read and write heads. These mechanical parts don't take shocks and impact well, but on the upside, this design also delivers a great combo of a low price and great storage capacity. The crucial criterion that determines the speed of a platter hard disk is RPM - the number of revolutions per minute. With the WD Blue 4TB, we have 5400 RPM RPM. This is a popular model for PCs and other devices meant for standard office work. Data transmission and stability is also impacted by the disk buffer - the so-called cache. The Western Digital hard disk is equipped with a 256 MB cache that stores the last used data for their speedy reading.

Connecting the Western Digital HDD

If you want to mount the WD Blue 4TB in your laptop or other device, it must have a 3.5" slot. All data transfer is done via the SATA III interface, boasting a standard speed of 6 Gbit/s. The technology is one of the most popular HDD data transfer solutions available and delivers a throughput of 600 MB/s.
