Hard Drive

20GB Ultra ATA/100 Hard Drive

• Storage Capacity: Hard drive storage capacity is measured in gigabytes. One gigabyte (GB) equals one thousand megabytes (MB). When calculating hard drive needs, consider the size and number of applications, whether you use your computer to edit video or to store large audio files. The larger the hard drive capacity, the more you'll be able to store on your hard drive.
• Rotational Speed: Rotational speed is a major factor in hard drive selection as it determines how quickly data can be retrieved. Typical rotational speeds are 5400 RPM or 7200 RPM. The higher the RPM (revolutions per minute), the less time you'll spend waiting for your computer to access files.
• Interface: The interface is the link between the hard drive and the computer used to transfer data. Most hard drives support either ATA-66 or Ultra ATA-100. Advanced Technology Attachment (ATA) is an industry standard interface: An Ultra ATA-100 hard drive is a faster interface than an ATA-66 hard drive.
