32x CD-RW Roundup Vol 2 - Page 13

RW Writing Tests

We used Nero 5.5.7.2 for writing CDs at the maximum RW speed for all the tested drives. The four of the five tested drives supports 12x re-writing speeds, while the Philips PCRW3210 supports 10x writing speed:

The CyberDrive CW-058D not only is the faster recorder but also the fastest re-writer. In case you don't remember, CyberDrive was the first manufacturer that ever introduced 12x re-writing speed with CW-038D model. Therefore the 394ses that needed for finishing the task could be expected. The Mitsumi CR-480ATE comes second with 406secs, AOpen CRW3248 third with 409secs, LiteOn forth with 413secs and Philips PCRW3210 last with 486secs.

The CyberDrive doesn't have any problem in writing 4-10x HS-RW at 12x. However the AOpen CRW3248 has problems writing at 12x, Mitsubishi Chemical's 4-10x HS-RW media. The produced CD wasn't readable. This can be fixed with newer firmware upgrade. When using certified 4-12x HS-RW media we didn't noticed any problems.

- Packet Writing Tests

We used Ahead InCD v3.21 for the packet writing tests with the LiteOn HS-RW media. The formatted disc had 534mbs 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 Windows Explorer (we dragged and dropped) and we completed the test twice to eliminate any possible time measurement faults and user errors:

The Mitsumi CR-480ATE and CyberDrive CW-058D are the two faster re-writers under the packet writing mode with 8.81X. The LiteOn LTR-32123S follows with 8.55X, AOpen CRW3248 with 8.35X and Philips PCRW3210 comes last with 7.1X. The AOpen CRW3248 takes the lead over the reading part with 23.17X.
