When referring to the speed of a CD-ROM drive, the 'x' symbol represents the multiple of the standard data transfer rate of a CD-ROM drive. For example, if a CD-ROM drive is labeled as 32x, it means that the drive can read data at a speed 32 times faster than the original speed of a CD-ROM drive.

The speed of a CD-ROM drive is typically measured in multiples of the original speed of the drive, which is 150 KB/s for audio CDs and 153.6 KB/s for data CDs. This means that a 32x CD-ROM drive can read data at a speed of 4.8 MB/s for audio CDs and 4.9152 MB/s for data CDs.

Higher 'x' ratings indicate faster data transfer rates, which can result in quicker access to data stored on the CD-ROM. This is particularly important when it comes to tasks that require reading large amounts of data from a CD-ROM, such as installing software or playing multimedia files.

It is worth noting that the 'x' rating only refers to the read speed of the CD-ROM drive. Write speeds for CD-ROM drives are typically lower than read speeds and are represented by a different 'x' rating. For example, a CD-ROM drive with a 32x read speed may only have a 16x write speed.

When shopping for a CD-ROM drive, it is important to consider both the read and write speeds of the drive to ensure that it meets your specific needs. For example, if you plan on burning a lot of CDs, you will want a drive with a higher write speed. On the other hand, if you primarily use your CD-ROM drive for playing music or watching movies, a drive with a higher read speed may be more important to you.

In conclusion, the 'x' symbol when referring to the speed of a CD-ROM indicates the multiple of the standard data transfer rate of a CD-ROM drive. Understanding the 'x' rating of a CD-ROM drive can help you choose the right drive for your specific needs.
