Q. Main drawbacks of CD-ROMs?

The main drawbacks of CD-ROMs are:

  • It is read only thus can't be updated
  • Access time is longer than that of magnetic disks.
  • Very slow as compared to hard disks that implies normal transfer rate is 300 Mbps for double speed drives and 600 Mbps for quadruple speed drives.
