The read speed of a CD-RW drive is indicated by the first number in the speed notation, which represents the speed at which the drive can read data from a CD. In this case, the drive advertises speeds of 32x/12x/48x, where: - 32x refers to the speed at which it can read standard CD-ROMs, - 12x refers to the speed at which it can write to CD-RW disks, - 48x refers to the speed at which it can write to CD-R disks. The read speed is the highest speed indicated before these writing speeds, which is 32x. However, the notation suggests that the drive has a higher maximum speed for reading new format CDs, which can potentially be indicated by the last number, specifically if it supports additional features or formats. In this case, the answer points to 48x, representing an optimal reading capability and thus reflects the maximum performance capability for reading standard CDs. Therefore, the highest number indicates the drive's reading speed capability.
