Other Hard Disk Features

The HDD boasts a unique design. Inside the hard drive there is a mechanism with moving platters, complete with disk read/write heads. These moving parts are not particularly resistant against shock or impact, but this design delivers its amazing price/capacity ratio. The crucial parameter that determines the speed of a HDD is RPM - the number of revolutions per minute. In case of the Seagate Exos X18 18TB 512e/4kn SAS, you get 7200 rev/min RPM. 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. System responsivity and stability is also determined by the disk buffer - the so-called cache. The Seagate HDD is equipped with a 256 MB cache that stores the last data inputs for their speedy reading.
