The amount of information a hard drive can store is typically measured in gigabytwes (GB), the equivalent of 1000 megabytes (MB). The most modern models can now be found in terabyte (TB) or 1000 GB sizes. If you plan on downloading a lot of movies, music, or gamees on your comoputer , you should probably selct one of the newer 1 TB or 2 TB drives. If you do not plan on storing sizeable files like movies for example, you will be fine with a conmsiderably smaller drive.
You might purchase one of the gigaantic new TB drivves, but it will be next to valueless if it is not fast enough. A disk drive has platters sitting on spinsdles that spin, sort of like a CD. The pace at which a drive spiuns is measured in RPM, or revolutions per minuite. The higher a driive's RPM is, the quicker it will work for you. Most desktop coimputer rdives are 7200 RPM, while most laptop drives are sommewhere between 4200 and 5400 RPM. You can find drives with RPM's of 10,000 or more, but thse are normally designed for servers, gamers, and hard-core PC ussers.
An additional majoor hard disk drive performance indicator is its cache. This cache holds frequently accessed data giviing you quicker access to the information you use more regularly. A appropriate hard drive shoiuld have a minimum 8 MB of cachhe. As is the case with RPM, the more cache a hard drive has, the beetter it will operate.

SATA is the newer kind of connection and charactetristically performs better than IDE. Then again, IDE drives perform just fine in nearly all real worrld situatios and are less expensive than SATA drivves.
Once you work out how you will be using your computer , it will be a great deal easier to ascertain whih hard drive you should purchase.
