WD Blue 4TB

The WD Blue 4TB hard drive is one of the classic internal HDDs for households and casual users. The 3.5" format is designed primarily for desktop PCs and data centres. One of the key characteristics is clearly the rotational speed (RPM). The 5400 RPM RPM should meet the needs of any ordinary user. The overall data capacity of the HDD is 4000 GB. The device has a 256 MB memory cache. All the data communication between the Western Digital hard disk and the PC or other devices takes place through the SATA III interface.

Other Hard Disk Features

The HDD boasts a unique design. The enclosure conceals a mechanism that uses moving platters accompanied by disk read/write heads. These mechanical parts don't take shocks and impact well, but at the same time you get an excellent price/storage capacity ratio. The crucial criterion that affects the speed of a HDD is RPM - the number of revolutions per minute. In case of the WD Blue 4TB, you would get 5400 RPM revolutions per minute. You can find these drives mainly in computers and other home devices that aren't built for high performance. System responsivity and overall stability is also influenced by the disk buffer - the so-called cache. The Western Digital hard drive features a 256 MB cache that keeps the last written data for their fast retrieval and reading.

Connecting the Western Digital HDD

In order to mount the WD Blue 4TB in your laptop or other device, it must be equipped with a 3.5" slot. All communication with the computer is done through the SATA III interface with a standard speed of 6 Gbit/s. The technology ranks among the most popular HDD data transfer solutions available and delivers a throughput of 600 MB/s.
