2. Data Tests


Data Tests

Test Method:
- SCSI Mechanic v3.0 & CD Speed 99 v0.80 Tests: With these tests we attempted to compare the I/O performance of TEAC's CD-516EB to other various CDR-W drives (see charts) and we also checked the drive performance. In all of our following tests we used a pressed CD containing PlexTools v1.08 original CD.

- SCSI Mechanic v3.0 results:

TEAC CD-W516EB gave quite good results at the Random and the Sequential I/O tests but it seems that it doesn't manage so good its internal cache memory as shown in the Same Sector I/O test. At the left part of the graph you can see a very good Random I/O performance (883), which can be explained due to the very good seek times of the drive. At the Sequential I/O test TEAC holds the second best performance with 4434 Kb/s following the leader PlexWriter PX-W1610A. As it seems Teac engineers needs to improve the drive mechanism in order to reach the top.

Not badly performing, TEAC CD-W516EB gave average data reading results according to the above chart. The drive started reading the PlexTools v1.08 pressed CD at a 17.69X and ended the session at 39.39X. Its average speed was 29.93X which places TEAC in the third result position behind the PlexWriter's and the Sanyo's CRD-BP1400P performances. Certainly TEAC could manage it better.

On the contrast, as you can see above it seems that TEAC engineers kept their promise for under 80ms random seek time. The results were beyond the competition and maybe are the best seeking results we ever had in our CD-RW drive tests. With no doubt, the fact will please the TEAC's future users, although someone might claim that seeking capability is not the major parameter for a CDR-W drive.

The TEAC 516EB with CDR media still doesn't manage to outpeform both PleXWriter PX-W1610A and Sanyo CRD-BP1400P...
