Other HDD Features

Platter hard disks have a notably special construction. Inside the enclosure there is a mechanism that utilises moving platters, complete with hard disk heads that facilitate reading and writing of data. These moving parts are not particularly resistant against shock or impact, but at the same time you get a great combo of a low price and great storage capacity. The crucial parameter that determines the speed of a hard disk is the number of rotations per minute (RPM). With the WD Purple Pro 18TB, you get 7200 RPM revolutions per minute. It's a great model for more demanding users, such as graphic or video editors - in short, people who work with large amounts of data. Data transmission and stability is also influenced by the disk buffer - the so-called cache. The Western Digital platter drive is equipped with a 512 MB cache that stores the last used data for their speedy reading.

Connecting the Western Digital Hard Drive

If you want to mount the WD Purple Pro 18TB in the device of your choice, it must be equipped with a 3.5" slot.
