The special utility for checking the performance of our drives when working with DVD-media ran with the same disks, as those we used in the previous test: a licensed movie DVD and its copy on a DVD-RW disk.
DVD-ROM | DVD-RW | |
LG GCC-4480B | Graph | Graph |
LG GCC-4320B | Graph | Graph |
Philips PBC03210G | Graph | Graph |
Samsung SM-348B | Graph | Graph |
Toshiba SD-R1202 | Graph | Graph |
Toshiba SD-R1312 | Graph | Graph |
So, what do we have here? The LG GCC-4480B couldn’t make it to its specified speed. With both media it managed to show the read speed slightly exceeding 6x. Moreover, we see a pretty big slump in the end of the graph for the printed disk.
The second LG drive, GCC-4320B, looks a little better. It copes perfectly well with the printed DVD and demonstrates a much higher read speed. But as it comes to DVD-RW disk, the read speed drops by the same 25% as that of the predecessor.
Philips PBC03210G shows about 4x read speed, which is less than could be expected. Moreover, it failed to read the DVD-RW disk to the end.
Samsung SM-348B nearly hit its specified speed, reading the DVD-ROM at more than 14x. The problems on the last section didn’t allow it to reach 16x: there are evident slumps in the graph. The DVD-RW didn’t tolerate such agility: the read speed was twice as low as that shown on the printed disk.
Toshiba SD-R1202 had every chance to reach the specified 12x on the DVD-ROM, but again the last stretch proved to be hard to pass. DVD-RW reading is not a strong point of this model: it managed to demonstrate no more than 5x.
Toshiba SD-R1312 behaves very similarly to the first Toshiba when reading the DVD-RW disk. With DVD-ROM disk it proves more stable (no slumps in the graph). However, its average read speed doesn’t exceed 8x.
Taking into account the seek time, we could say that the best performance here belongs to LG GCC-4480B and Samsung SM-348B, which are the fastest so far. Philips PBC03210G proved the slowest, judging by the only test it passed.
Traditionally, the two Toshiba drives loaded the CPU most of all. But every rule has exceptions. This way, LG GCC-4480B utilized about 17% of the CPU resources in one of the tests under maximum workload, which is rather high.
Among other results, we could point out at the noticeably higher recognition time of the DVD-RW, although Philips PBC03210G is not quick to recognize the DVD-ROM, either.
