The Western Digital WD800AAJB 80GB is a 3.5" 80GB Hard Disk Drive.
It uses the IDE interface and has a speed of 7200 RPM.
|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||80GB||The drive storage capacity is the limit to the size of files that can be stored|
|Release Date||01 Jun 2004||The later the release, the more likely manufacturer support will still be around|
|Cache Size||8MB||The bigger the cache, the more data that can be temporarily stored for faster access|
|Power Required||6W||HDDs should generally require very little power to run, and SSDs even less|
|RPM||7200 RPM||The higher the RPM, the faster the hard drive, and the faster stored data can be accessed|
|Drive Interface||IDE||The interface is the type of motherboard connection and defines the bandwidth limit of the drive|
The Western Digital WD800AAJB 80GB 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 WD800AAJB 80GB is a bottom of the range hard disk drive, and should only ever be used as basic data storage.
With a cache of 8MB, the Western Digital WD800AAJB 80GB 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 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 80GB, the Western Digital WD800AAJB 80GB has a tiny amount of storage space for an hard disk drive. The IDE interface is now obsolete, so this hard disk drive would be a poor choice in a modern build. However, it would still function as a very low-end storage device.
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.
