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.

The SM-352 has middle of the road seek times, and a curiously slow disk recognition & eject time. Compared to some of the other drives however, the SM-352 is not out of range. CPU utilization is pretty good, and the average speed of 32.67X is good as well.

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.

The average speed of the SM-352 is again good, near the top of this list with Audio media. Seek times are moderate, and CPU utilization at 8X is substantial (100%). The drive is also slower at recognizing CD's as well as ejecting and loading CD's then most of the other drives listed here.
