Pioneer DVR-A04 IDE DVD-R/RW - Page 7

HS-RW Writing Tests

We used Nero 5.5.7.8 for writing CD's with the maximum RW writing speed (4X) for the Pioneer DVR-A04. Note that the test result from DVR-A03 comes with normal CD-RW media:

The Pioneer drives need around 20mins to finish the task, due to its low (4X) re-writing speed. The erase time is 50 secs, 3 seconds faster than the previous model.

- CD Packet Writing Tests

We used Ahead InCD v3.21 for all Packet Writing tests. We used TDK HS-CD/RW media and we formatted it. The formatted disc revealed 530mbs of free space. We copied a 403 MB file (403.147 kbs) from a Hard Disk (on the same PC as the writers) to the formatted RW media-using explorer (we dragged and dropped) and we completed the test twice to eliminate possible time measurement faults and user errors:

The Pioneer DVR-A03 supports only 2.4X writing and 2.8X reading speeds with a packet written formatted RW disc.

- DVD-RW packet writing tests

Using a blank DVD-RW disc, you can format the disc with the UDF 1.5 format and then use it like a normal CD packet-writing medium.

-Test Results

We used the same file/methodology that we are used for our CD packet-writing test. The drive needs 5:01mins to write the file and 4:50mins to read it. That can be translated in 0.98X writing and 1.00X reading (X factor = 1385Kb/s). The erase time is also shorten to 2 minutes.
