The Western Digital WD15EARS 1.5TB is a 3.5" 1500GB 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||1500GB||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|
|Power Required||5W||HDDs should generally require very little power to run, and SSDs even less|
|Drive Interface||SATA 6Gb/s||The interface is the type of motherboard connection and defines the bandwidth limit of the drive|
The Western Digital WD15EARS 1.5TB 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 WD15EARS 1.5TB is a fairly poor primary hard disk drive choice, as its performance leaves a lot to be desired. It would be fine to use as basic data storage, though.
With a cache of 64MB, the Western Digital WD15EARS 1.5TB 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 1500GB, the Western Digital WD15EARS 1.5TB has a decent amount of storage. 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.
