CD Speed is a CD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular test we use a pressed CD-ROM with about 640MB of data as the test disk. Using a CDR or CDRW as the test disk may (or may not) impact the results slightly, so the pressed disk is the de facto standard.

There really isn't too much variation under the standard CDROM data tests here. The average speed for the LG 32x10x40x was 30.46x, but towards the end of the disk the drive did reach speeds of about 37X. CPU usage at 4X jumps up to 20% - and that is something we tested twice - which is a little bit out of the loop. Everything else looks pretty much where you'd expect it to be.

CD Speed is a CD-ROM benchmark which can test the most important features of a CD-ROM drive. In this particular test we use a pressed Audio CD with about 65 minutes of audio on it as the test disk. CDROM's in general have a harder time processing audio data, and hence the results can be drastically slower than that of data tests alone.

Audio disk benchmarks show peg the LG 32x10x40x in a middle of the road position. It is not the fastest drive we've tested, but it manages to out-perform a few of the Samsung CDRW's we have tested in the past.
