The Western Digital WD20EFRX 2TB is a 3.5" 2000GB Hard Disk Drive.
It uses the SATA 6Gb/s interface.
|Drive Type||Hard Disk Drive||This defines whether the drive is a large-capacity slower hard disk drive, a smaller-capacity but much faster solid-state drive, or a hybrid|
|Physical Size||3.5"||The size of the drive dictates which drive bays it will fit into - generally a small drive will fit into any bigger drive bay with an adapter|
|Capacity||2000GB||The drive storage capacity is the limit to the size of files that can be stored|
|Cache Size||64MB||The bigger the cache, the more data that can be temporarily stored for faster access|
|Drive Interface||SATA 6Gb/s||The interface is the type of motherboard connection and defines the bandwidth limit of the drive|
The Western Digital WD20EFRX 2TB is a hard disk drive, which means it stores data using quickly rotating disks, or platters, that can be read and written on via the moving actuator arm. Hard disk drives generally have a large storage capacity, and so are perfect for large amounts of data. The potential performance is well below that of solid-state drives, but they can definitely still hold their own. The Western Digital WD20EFRX 2TB is a good example of a high performance hard disk drive, and should complement any PC build as a primary storage device.
With a cache of 64MB, the Western Digital WD20EFRX 2TB can store an extremely large amount of data temporarily, which will result in much faster loading times for previously loaded files and applications. At a speed of 0 RPM, the hard disk drive spins at a very slow speed. This speed should be avoided entirely unless used as a dedicated storage system, as the resulting performance would be infuriatingly slow.
With a capacity of 2000GB, the Western Digital WD20EFRX 2TB has a very large amount of storage for just one hard disk drive. Using the SATA 3.0 6Gb/s interface this hard disk drive will never be limited by its connection with the motherboard. In fact, mechanical hard disk drives cannot even reach the bandwidth capacity allowed by SATA 2.0 3Gb/s, so it would not matter even if it were plugged into a SATA 2.0 motherboard slot.
A form factor size of 3.5" is standard for desktop drives, and this will fit into any standard case drive bay, or into a 5.25" drive bay with an adapter.
