The WD Red 12TB hard drive is one of the high load internal HDDs for NAS systems. 3.5" HDDs are designed chiefly for data centres and desktop PCs. One of the crucial parameters is clearly the rotational speed of the HDD. 5400 RPM should satisfy the demands of any casual user. You can look forward to a total data capacity of 12000 GB. The drive uses a 256 MB memory cache. The data transfer is facilitated via the SATA III interface.
Standard HDDs are notable for their construction. The enclosure conceals a mechanism that uses moving platters accompanied by hard disk heads that facilitate reading and writing of data. These moving parts can be damaged by a shock or impact, but this weak point is well-compensated by its amazing price/capacity ratio. The key parameter that affects the speed of a HDD is the number of platter revolutions per minute, generally known as RPM. With the WD Red 12TB, you would get 5400 RPM RPM. These drives are generally used in laptops and other devices meant for casual home use. Data transmission and stability is also determined by the disk buffer - the so-called cache. The Western Digital hard disk features a 256 MB cache that keeps the last written data for their prompt retrieval and reading.
In order to mount the WD Red 12TB in your PC or other device, it requires a 3,5" slot. All data transfer 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 throughput of 600 MB/s. The dimensions of the HDD are 101,6 × 147 × 26,1 mm.
