The last 6 diagrams demonstrate the work of our testing participants with the CD-DA disk:

The LG GCC-4480B drive was the most stable at reading various types of media. The difference in its average speeds was very small, and the results exceeded 30x. Samsung SM-348B was the fastest on three media types, but the general impression was somewhat spoiled when it came to the audio CD. The same is true for Philips PBC03210G, while both Toshiba drives suffered a significant performance drop in case of CD-RW and CD-DA disks. LG GCC-4320B also trips over the CD-RW disk.

LG GCC-4480B boasts the lowest seek time. Formally, Philips PBC03210G is the winner, but it showed quite indecent numbers of a few milliseconds. We would consider it some error in the benchmark. Toshiba drives are the losers here and perform even worse when reading the audio CD.

In the CPU utilization test, the results of Philips PBC03210G look very strange: they float up and down without any order. In some cases, the 1x speed produces a higher workload onto the CPU than higher speeds. Toshiba drives are also hungry for CPU resources. The benchmark suggests that Toshiba SD-R1202 is the record-holder in this respect: it loads the CPU to the full 100% on the CD-R disk. Samsung SM-348B also behaves strange when working with the audio CD: it doesn’t consume too many CPU resources from the start, but then gets hungrier and hungrier.

You can look up other results in the table: they are more unified, except the interface data transfer rate. But this parameter is often measured wrong by the program.
