Other HDD Features

The HDD boasts a unique design. Inside the hard drive there is a mechanism that utilises moving platters, complete with disk read/write heads. These mechanical parts are admittedly more sensitive to shocks, but this design delivers an excellent price/storage capacity ratio. The crucial parameter that affects the speed of a hard drive is the number of revolutions per minute (RPM). In case of the Seagate IronWolf 8TB CMR, you get 7200 RPM revolutions per minute. This is great news for people who demand more from their devices, such as graphic designers, gamers, video editors, and people who tend to use large amounts of data.

The Seagate hard drive features a 256 MB cache that keeps the last written data for their fast retrieval and reading.
