Other Hard Disk Features

Standard HDDs are notable for their construction. Inside the enclosure there is a mechanism with moving platters, complete with hard disk heads that facilitate reading and writing of data. These moving parts can be damaged by a shock or impact, but this weak point is well-compensated by its amazing price/capacity ratio. The key criterion that determines the speed of a hard drive is the number of revolutions per minute (RPM). In case of the WD Purple 18TB, you get 7200 RPM revolutions per minute. This is welcome news for people with higher requirements, for example video editors, graphic artists, people who play PC games, and everybody else who deal with large amounts of data. File access speed and stability is also affected the embedded buffer memory known as cache. The Western Digital platter drive includes a 512 MB cache that stores the last data inputs for their speedy reading.
