RW Writing Tests

The Yamaha CRW2100S doesn't support real 10x (CLV) writing speed with HS RW media. It supports 4x-10x (Full CAV) recording speed in Fixed Packet Writing. We used Nero 5.0.4.0 for writing CDs in maximum RW writing speed for all the tested drives. Yamaha CRW2100S of course since it didn't supported 10x writing gave the bigger time with 599 sec when the (guess...) Plextor PX-W1610A had the best (488sec) while the other drives gave 490sec (TDK) and 492sec (Sanyo). The Yamaha also came up with the biggest erase time when erasing HS RW media:

- Packet Writing Tests:
We used Ahead InCD v1.80 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. Below is the properties tab for the Yamaha CRW2100S. Even we selected the 10x write option the drive seems to ignore that and returned to 8x option automatically. (Same case with it's brother CRW2100E)

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:

Yamaha CRW2100S comes second in packet writing after the PX-W1610A (Yamaha gave us 4.9x when the Plextor came up with 7,12x). The other 2 drives are slower when writing/reading HS RW media in packet writing mode: (Sanyo: 4.51x, TDK: 4.77x).

Verdict of CDR-W Results:
The Yamaha CRW2100S certainly is not the best choice for RW writing. Even though the drive supports the new HS RW writing mode, it fails to achieve the higher (10x) writing speed of it. The competition supports 10x writing and CRW2100S has no luck against it. Even in the packet-writing test, which Yamaha supposed to support 10x, the speed is not exactly this. It begins with 4x and increases to 10x at the end of the disc. That is probably why the results were that low (4.96x writing). The competition however (TDK, SANYO) is worse, with only the Plextor drive overwhelming the Yamaha by 32% faster...
