The hard drive is one of the most frequently upgraded
parts of a computer. Its function is to store the user's
programs, data, and operating system files. How much hard
drive space one needs depends heavily on the individual
user; however, it's also fairly easy to tell. If you are
having to delete things off your computer due to lack
of space, it may be time to invest in a new hard drive.
Luckily, due to their strict adherence to standards, almost
any computer running at least Windows 95 can upgrade their
hard drive with minimal problems.
Nearly all computers will allow you to run two hard
drives at once, you can keep your original data in place
and either use the new drive for additional storage
or install a new operating system on it. See upgrading
your OS.
As for other drives, a CD-RW drive (A.K.A. "CD
Burner") is an excellent upgrade, providing both
an alternative to buying a larger hard drive, and a
means of backing up important files. A DVD-ROM drive
can turn your computer into a DVD player for half the
cost of most commercial solutions.
Best of all, all of these drives tend to follow the
IDE standard specification, which means that you can
essentially just pick them up, put them in your machine
(or have someone put them in for you) and you are done.
