RW Writing Tests

We used Nero 5.5.7.9 for writing CDs at the maximum RW speed for all the tested drives. TEAC CD-W524E needs 6:50mins to end the task, taking the third place, behind Plextor and LiteOn drives. The erase times are higher than LiteOn but the same as the Plextor drive:

- Packet Writing Tests

We used Ahead InCD v3.24.3 for all Packet Writing tests with a Ricoh HS-RW media. The included TEAC 4-10x doesn't support 12x re-writing. The formatting of the media takes around 11 minutes. 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:

TEAC CD-W540E has the third best packet writing performance. The differences however with the two faster drives are down to 0.01X-0.04X, which have no practical sense. At the reading part the drive has the lowest reading performance of 8.45X.

TEAC explained the reduced packet-writing reading speed "…If the CD-RW disc used is other than Ricoh HS CD-RW, TEAC CDW540E will write at 10X at 32 blocks of user date and 7 link blocks per Packet (= 39 blocks/packet). The actual transfer rate will be 32/39*10x which is approx. 8.2x. The read speed after write will be maintained as write speed. With other vendors' drive, when the drive reads the data after write, it read at the same speed during write however, after reading certain blocks or certain time period, the drive will spin-up to 32x or 48x…"
