WD15EARS 1.5TB compatibility review

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.
