RW Writing Tests

We used Nero 5.0.3.1 for writing CDs in maximum RW writing speed for all the tested drives. All other drives write at 10x RW writing speed except Yamaha CRW2100E since it supports only 8x re-write:

Both Sanyo drives gave the same time 491 secs in the HS RW writing test. Plextor PX-W1210S gave the lowest time (3 sec less) and Yamaha gave the highest time (due to 8x re-write speed). The erase times also are similar for both Sanyo drives.

- Packet Writing Tests

We used Ahead InCD v1.70 for all Packet Writing tests. We used Ricoh HS RW media and we formatted it. The formatting of the media takes around 10min. After formatting, we tested all four drives for their packet writing performance.

The formatted disc had 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) we completed the test twice to eliminate possible time measurement faults and user error:

The results shows that both Sanyo drives have low packet writing performance (compared to Plextor's). The BP4 model wrote at 5.68x and the BP1400P at only 4.51x. The reading of packet formatted CDs is better but still needs improvement.
