WD Blue 3TB

The WD Blue 3TB hard disk belongs among the classic internal HDDs for households and casual users. 3.5" HDDs are designed primarily for desktop PCs and data centres. One of the main parameters is undoubtedly the rotational speed of the HDD. The 5400 RPM RPM meets the needs of any casual user. The total capacity of the hard drive is 3000 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 via the SATA III interface.

• Standard hard drives are admittedly more susceptible to physical damage, but they are also more affordable than the newer SSDs

Other HDD Features

Standard HDDs are notable for their construction. Inside the drive there is a mechanism with moving platters, complete with hard disk heads that read and write the data. These mechanical parts are admittedly more sensitive to shocks, but this weak point is well-compensated by an excellent price/storage capacity ratio. The key criterion that determines the speed of a platter hard disk is the number of revolutions per minute (RPM). With the WD Blue 3TB, we have 5400 RPM RPM. This is a popular model for PCs designed for effective office work but nothing particularly performance-intensive. System responsivity and stability is also influenced by the disk buffer - the so-called cache. The Western Digital hard drive includes a 256 MB cache that stores the last used data for their fast retrieval and reading.

Connecting the Western Digital Hard Disk

In order to mount the WD Blue 3TB in your computer or other device, you need a 3.5" slot. Data transfer happens via the SATA III interface with 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.
