The X-Factor: CD-ROM Performance
Not unlike hard drives, CD-ROM drives have a number of factors that will determine how well they will perform.
The original CD-ROMs had a transfer rate of 150KB per second. Of course the technology improved and newer CD-DOM drives boasted a 300KB per second transfer rate.
So the marketing gurus got together and said, "why don't we call this a 2X drive, you know, twice the speed of the original CD-ROM." The public ate this up, and now we have this ambiguous X-factor that is supposed to tell us the performance of the drive.
The biggest mistake people make is to assume that a 30X drive has a transfer rate of 30 x 150KB/s = 4500 KB/s. As you will see there are many factors that go into determining a CD-ROMs overall performance.
