How to Choose a Quality
Cheap Hard Drive
Next to the CPU
and motherboard, the most critical computer component is the hard drive. A slow
hard drive will lessen the apparent speed of even the fastest CPU and will
drop the performance of the entire system--sometimes dramatically. Matching
the hard drive to your motherboard and CPU will result in better fine tuned system.
Also, getting the right hard drive for the type of usage it will receive are
important buying decisions. So, how do you determine the best hard drive for
your computer? Here are some ideas to keep in mind when choosing your hard
drive.
- Select a hard drive with a capacity of at least 8 GB.
- Look for a 8 millisecond or less for the average seek time.
- Buy a hard drive with the fastest and latest IDE or SCSI interface.
- Make sure that the cabling and interface will support your drive.
In addition, the
following table may help in making the decision on the right hard drive for
the way you plan on using your system. All systems do not need the biggest
and latest hard drive. Like surfing the Internet with a dial-up modem, the
computer is limited to the download speed of the modem. Use the following
table as a basic guideline for choosing a hard drive based on the use it
will receive.
