The WD Red 8TB hard disk is one of the high load internal HDDs for NAS storage solutions. The 3.5" format is designed primarily for data centres and desktop PCs. One of the main parameters is clearly the number of revolutions per minute (RPM). 5400 RPM should satisfy most ordinary PC users. The overall data capacity of the HDD is 8000 GB. The drive features a 256 MB memory cache. The data transfer is facilitated using the SATA III interface.
Platter hard disks have a notably special construction. Inside the enclosure there is a mechanism that uses moving platters accompanied by disk read and write heads. These mechanical parts don't take shocks and impact well, but this weak point is well-compensated by its amazing price/capacity ratio. The important criterion that determines the speed of a platter hard disk is the number of revolutions per minute (RPM). With the WD Red 8TB, we have 5400 RPM revolutions per minute. You can find these drives mainly in laptops and other home devices that aren't built for high performance. Data transmission and overall stability is also significantly affected by the disk buffer - the so-called cache. The Western Digital HDD includes a 256 MB cache that stores the last used data for their speedy reading.
If you want to mount the WD Red 8TB in your PC or other device, you need a 3,5" slot. All communication with the computer is done through the SATA III interface, boasting a standard speed of 6 Gbit/s. The technology is one of the best HDD data transfer options available and delivers a speed of 600 MB/s. The dimensions of the HDD are 101,6 × 147 × 25,4 mm.
