The drive is a multi-function device. Since the drive is also capable of reading at up to 32X Max. (4,800 kilobytes per second) it is a good general use CD-ROM drive as well as recorder.

The speed at which a CD-ROM is written does not affect the speed at which that CD-ROM can be read. For example, a CD-ROM which was written at 2X can be read at 1X, 2X, 4X, 8X, 12X, 24X and so on.

Buffer

The Spressa CD-RW Recorder drive has a two or four megabyte data buffer, which reduces buffer underruns when writing to CD-RW and CD-R media with some software. Buffer underrun is a condition where the drive’s buffer runs out of data while the CD-R or CD-RW media is still being written. The recording of a CD is a system intensive process with some software, and the recorder needs a constant stream of data. A buffer underrun occurs when the data stream to the recorder is not fast enough to keep the recorder’s buffer full, causing the recording to abort.
