Drive TypeHard Disk DriveThis 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 Size3.5"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
Capacity750GBThe drive storage capacity is the limit to the size of files that can be stored
Release Date01 Dec 2010 The later the release, the more likely manufacturer support will still be around
Cache Size64MBThe bigger the cache, the more data that can be temporarily stored for faster access
Power Required5WHDDs should generally require very little power to run, and SSDs even less
RPM5400 RPMThe higher the RPM, the faster the hard drive, and the faster stored data can be accessed

WD7500AARS 750GB compatibility review

The Western Digital WD7500AARS 750GB 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 WD7500AARS 750GB 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 WD7500AARS 750GB 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 5400 RPM, the hard disk drive spins at a below average speed. This speed is common for laptop hard drives, and may have long-term reliability and low-power benefits, but the resulting hard drive performance is noticeably slow.

With a capacity of 750GB, the Western Digital WD7500AARS 750GB has a fairly small amount of storage for an hard disk drive. Using the SATA 2.0 3Gb/s interface this hard disk drive will not be limited by its connection with the motherboard, and there is currently no real reason to choose SATA 3.0 over SATA 2.0 for a mechanical hard disk drive (SSDs are another matter).

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.
