Unfortunately, IDEdrives have some serious shortcomings that you should keep in
mind. First, the IDE controller on the master drive requires a lot of CPU time to read
or write data. Although IDE drives may have a high data-transfer rate, the CPU is
going to have to do a lot of work to make it happen.
Second, remember that both the primary and secondary IDE channels on your
system can have two IDE devices connected to it, resulting in a total of four drives
in a typical system. Keep in mind that many different types of IDE drives have been
manufactured over the years. Early IDE drives transmitted data at around only
15MBps. Later-generation IDE drives can transfer data at speeds up to 133MBps. If
you connect an older, slower drive to an IDE channel with a newer drive, the newer
drive will slow down to the speed of the old drive. The entire channel will operate
at the speed of the slowest device connected to it.
Finally, attaching two devices to the same IDEchannel can slow things down
because a single drive controller must manage two devices.
