Other Hard Drive Features

Platter hard disks have a notably special construction. Inside the enclosure there is a mechanism with moving platters, complete with hard disk heads that read and write the 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 key criterion that affects the speed of a platter hard disk is RPM - the number of revolutions per minute. With the Seagate Exos X20 20TB SAS, we have 7200 rev/min revolutions per minute. This is ideal for demanding users, such as graphic designers, gamers, video editors, and people who tend to use large amounts of data. System responsivity and overall stability is also significantly affected by the disk buffer - the so-called cache. The Seagate platter drive is equipped with a 256 MB cache that stores the last used data for their fast retrieval and reading.
