WD Red Pro 12TB HDD Speed

Standard HDDs are notable for their construction. Inside the hard drive there is a mechanism with moving platters accompanied by disk read/write heads. These mechanical parts don't take shocks and impact well, but at the same time you get a great combo of a low price and great storage capacity. The key parameter that affects the speed of a platter hard disk is RPM - the number of revolutions per minute. In case of the WD Red Pro 12TB, you would get 7200 RPM revolutions per minute. This is great news for people who demand more from their devices, such as graphic or video editors - in short, people who work with large amounts of data. Data transmission and overall stability is also affected the embedded buffer memory known as cache. The Western Digital platter drive is equipped with a 256 MB cache that stores the last data inputs for their speedy reading.
