HS-RW Writing Tests

We used Nero Burning Rom for writing CDs in the maximum RW speed supported by the Panasonic LF-D521. The drive supports 8x maximum rewriting speed.

The Panasonic LF-D521 finished in 9:50 minutes, and needed just 29 seconds to perform the "quick erase" task under Nero. The DVR-A05 is slightly slower needing 9:57sec.

- Packet Writing Tests

We used InCD and Plextor HS-RW media for all Packet Writing tests. The formatting of the media takes around 10min. The formatted disc had 530mbs of free space. We copied a 403 MB file (403.147 kbps) from a Hard Disk (on the same PC as the writers) to the formatted RW media, using explorer (we dragged and dropped). We completed the test twice to eliminate possible time measurement faults and user handling errors:

In the writing part, both Panasonic and Pioneer drives gave the same average writing speed, around 5.6x. The reading task was faster for the Panasonic LF-D521, finishing at a 7.68x reading speed.
