In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), the same speed of compact disc players without buffering. As faster drives were released, the write speeds and read speeds for optical discs were multiplied by manufacturers, far exceeding the dri… Web1 nov. 2011 · Optical Drive Performance Specifications. Many factors in a drive can affect performance, and several specifications are involved. Typical performance figures published by manufacturers are the data transfer rate, the access time, the internal cache or buffers (if any), and the interface the drive uses.
