The WD Red 3TB hard drive belongs among the high load internal HDDs for the NAS storage solution environment. 3.5" HDDs are designed chiefly for desktop PCs and data centres. One of the main characteristics is undoubtedly the rotational speed of the HDD. The 5400 RPM RPM should meet the needs of most ordinary PC users. The total capacity of the hard drive is 3000 GB. The drive uses a 256 MB memory cache. The data transfer between the Western Digital hard drive and a computer or other device takes place via the SATA III interface.
Platter hard disks have a notably special construction. Inside the enclosure there is a mechanism with moving platters accompanied by hard disk heads that read and write the data. These moving parts can be damaged by a shock or impact, but on the upside, this design also delivers its amazing price/capacity ratio. The crucial parameter that determines the speed of a HDD is RPM - the number of revolutions per minute. In case of the WD Red 3TB, you can look forward to 5400 RPM revolutions per minute. This is a popular model for PCs and other devices meant for standard office work. System responsivity and overall stability is also significantly affected the embedded buffer memory known as cache. The Western Digital platter drive includes a 256 MB cache that keeps the last written data for their prompt retrieval and reading.
In order to mount the WD Red 3TB in the device of your choice, it requires a 3.5" slot. Data transfer is done via the SATA III interface with a standard speed of 6 Gbit/s. This technology is one of the best HDD data transfer options available and delivers a speed of 600 MB/s.
