Pioneer DVD-104S DVD ROM

Pioneer DVD-104S IDE DVD ROM - Page 3

Test Method:
I used CD Speed 99 v0.6, DVD Speed v0.01 and SiSoft SanDVDa 99 v8.5.30 to run Data tests. I run all tests with DMA On. All tests done at least 3 times ,took worst results, with same CD.

CD Speed results: (Speed : Bigger is better, Seek Times : less is better, CPU Usage : less is better)

	DVDive Index	Track Speed (ppm)	Buffered Read (mb/s)	Sequential Read (mb/s)	Random Read (kb/s)	Average Access Time (ms)
Data On	1956	9964	132	2.820	661	30

True Use Test:
Copyed an mpg file (678MB) from Pioneer DVD-104s into Quantum 6.4 in 162 sec (27.90x) (CPU Usage was around 13%). We also used it as souce DVDive for writing CDs at 8x, 12x and in all tests performed ok.

Verdict of Data Tests:
Pioneer specification indicates that the DVDive has 2.58mb/s - 6.0mb/s data transfer rate. Read Data Tests showed that it has minimum 2.5mb/s and average was 4.5mb/s. Those speeds would make every user happy. Notice the impressive seek time (75ms for random) and CPU usage (even on full speed it reached 58%). However, the DVDive didn't perform so well in Sisoft SanDVDa tests. Pioneer DVD-104s will satisfy its owners since will it will work fast enough for Data tasks.
