The WD Red 2TB hard disk ranks among the high load internal HDDs for NAS and ordinary data centres. 3.5" HDDs are designed mainly for desktop PCs, data centres, and other data-processing devices. One of the most important characteristics is clearly the rotational frequency (RPM). 5400 RPM should satisfy the demands of most typical users. You can look forward to a total data capacity of 2000 GB. The storage has a 64 MB memory cache. All the data communication takes place using the SATA III interface.
Standard HDDs are notable for their construction. Inside the hard drive there is a mechanism that utilises moving platters, complete with hard disk heads that facilitate reading and writing of data. These mechanical parts are admittedly more sensitive to shocks, but this design delivers a great combo of a low price and great storage capacity. The key criterion that determines the speed of a HDD is RPM - the number of revolutions per minute. In case of the WD Red 2TB, you would get 5400 RPM revolutions per minute. This is a popular model for laptops and other devices meant for casual home use. System responsivity and overall stability is also influenced by the disk buffer - the so-called cache. The Western Digital hard disk features a 64 MB cache that stores the last used data for their prompt retrieval and reading.
If you want to install the WD Red 2TB in your computer or other device, you need a 3,5" slot. The communication between the HDD and PC takes place through the SATA III interface, boasting a standard speed of 6 Gbit/s. The technology ranks among the most popular HDD data transfer options available and delivers a speed of 600 MB/s. The dimensions of the hard disk are 101,6 × 26,1 × 147 mm.
