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.

: Bigger is better, Seek Times : less is better, CPU Usage : less is better)

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.
