Other HDD Features

Standard HDDs are notable for their construction. Inside the enclosure there is a mechanism with moving platters accompanied by hard disk heads that read and write the data. These moving parts are not particularly resistant against shock or impact, but this weak point is well-compensated by an excellent price/storage capacity ratio. The crucial parameter that affects the speed of a HDD is RPM - the number of revolutions per minute. With the WD Blue 8TB, you would get 5640 RPM RPM. Data transmission and overall stability is also significantly affected by the disk buffer - the so-called cache. The Western Digital hard drive includes a 128 MB cache that stores the last used data for their fast retrieval and reading.
