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 Size2.5"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
Capacity640GBThe drive storage capacity is the limit to the size of files that can be stored
Release Date01 Jan 2012 The later the release, the more likely manufacturer support will still be around
Cache Size16MBThe bigger the cache, the more data that can be temporarily stored for faster access
Power Required6WHDDs should generally require very little power to run, and SSDs even less
RPM7200 RPMThe higher the RPM, the faster the hard drive, and the faster stored data can be accessed

HTE727564A9E364 640GB compatibility review

The Hitachi HTE727564A9E364 640GB 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 Hitachi HTE727564A9E364 640GB is a decent primary hard disk drive choice, but its performance is somewhat lacking.

With a cache of 16MB, the Hitachi HTE727564A9E364 640GB can store a relatively small amount of data temporarily, which will result in fast loading times but only for a small amount of previously loaded data. At a speed of 7200 RPM, the hard disk drive spins at about the market average for desktop PCs. This speed is widely considered the desktop standard, providing a good balance between reliability, cost, performance, and noise.

With a capacity of 640GB, the Hitachi HTE727564A9E364 640GB 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 2.5" is standard for laptop drives and solid-state drives, and this will fit into any 2.5" drive bay. These drive bays are not yet ubiquitous, but it will also fit into a standard 3.5" or 5.25" drive bay with the appropriate adapter.
