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
Capacity320GBThe drive storage capacity is the limit to the size of files that can be stored
Cache Size8MBThe 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

ST320LT020-9YG142 320GB compatibility review

The Seagate ST320LT020-9YG142 320GB 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 Seagate ST320LT020-9YG142 320GB 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 8MB, the Seagate ST320LT020-9YG142 320GB can store a very small amount of data temporarily. Loading data that has previously been loaded will result in barely any difference in access speed and load duration. 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 320GB, the Seagate ST320LT020-9YG142 320GB has a very small amount of storage space for an hard disk driveUsing 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.
