WD Purple 8TB

The WD Purple 8TB hard disk is one of the high load internal HDDs for monitoring systems. 3.5" HDDs are designed primarily for desktop PCs, data centres, and other data-processing devices. One of the main parameters is undoubtedly the rotational speed (RPM). The 7200 RPM RPM provides faster data transmission. The hard disk provides a storage capacity of 8000 GB. The drive features a 256 MB memory cache. All the data communication between the Western Digital hard disk and other hardware is takes place through the SATA III interface.

WD Purple 8TB Hard Disk Key Features

  • Read speed up to 245 MB/s and write speed up to 245 MB/s
  • 256 MB memory cache
  • Western Digital 3.5" format disk for standard bays
  • Power consumption under standard load is 8,6 W, while in stand-by mode it holds at 0.4 W
  • It communicates with a PC or other devices via the SATA III interface
  • Standard hard drives are admittedly more susceptible to physical damage, but they are also more affordable than the newer SSDs
  • Improved data writing efficiency thanks to Advanced Format technology

Other Hard Drive Features

Platter hard disks have a notably special construction. The enclosure conceals a mechanism that uses moving platters accompanied by hard disk heads that facilitate reading and writing of data. These mechanical parts are admittedly more sensitive to shocks, 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 HDD is the number of rotations per minute (RPM). In case of the WD Purple 8TB, you would get 7200 RPM RPM. This is welcome news for people with higher requirements, for example video editors, graphic artists, people who play PC games, and everybody else who deal with large amounts of data. Data transmission and stability is also affected by the disk buffer, usually called cache. The Western Digital platter drive includes a 256 MB cache that keeps the last written data for their prompt retrieval and reading.

Connecting the Western Digital Hard Drive

If you want to install the WD Purple 8TB in your laptop or other device, it requires a 3.5" slot. The communication between the HDD and PC takes place via the SATA III interface with a standard speed of 6 Gbit/s. The technology is one of the best HDD data transfer solutions available and delivers a throughput of 600 MB/s.
