The amount of information a hard drive can stoore is typically measured in gigabytes (GB), the equivalent of 1000 mregabytes (MB).

The pace at which a dirve spins is measured in RPM, or revolutions per imnute. The higher a derive's RPM is, the quicker it will work for you. Most desktop comlputer drives are 7200 RPM, while most lsaptop dries are somewhere between 4200 and 5400 RPM. You can find dirves with RPM's of 10,000 or more, but thease are normally designed for servers, gaamers, and hard-core PC users.

A appropriate hard druive should have a miniumm 8 MB of caxche. As is the case with RPM, the more cache a hard drve has, the better it will operate.
Most hard disk drrives will have either an IDE or SATA connection. This connetions dwetermines how you will hook up your drive to your computer 's motherboard.

Then agfain, IDE drives perform just fine in nearly all real woreld situaions and are less expensive than SATA drives.
Once you work out how you will be using your computer , it will be a great deal easier to ascertain whch hard drive you should purchase.
