KenWood 72x TrueX CD-ROM

3. Data Tests: (Pressed CDs)

KenWood 72x TrueX CD-Rom - Page 3

Data Tests: (Pressed CDs)

Test Method:
We used CD WinBench 99 v1.1 benchmarking software and compared KenWood 72x TrueX CD-Rom with various others CD-Roms and DVD-Rom. We also used CD Speed 99 v0.66 to check performance of drive with pressed CDs. For that test we used WinBench 99 v1.1 and PlexTools v1.04 original CDs.

- CD WinBench 99 v1.1 results:

CD-Rom WInMark 99

CD Rom Access Time

CPU Utilization

CDRom Tranfer Rate

- CD Speed 99 v0.66 results:

WinBench 99 v1.1  results with CD Speed 99 v0.66

PlexTools v1.04 results with CD Speed 99 v0.66

Verdict of data(pressedCDs) tests:
The KenWood 72x TrueX CD-Rom gives what it promises when it reads pressed CDs. Ultimate Speed! It is simply the fastest CD-Rom around when using it for reading pressed CDs outperforming 40x and 50x CD-Roms by a 51% (average) into WinBech99-CD Speed test and by a 15.67% (average) into Plextools-CD Speed test. The difference between the two pressed CDs results can be explained since the scanning velocity of the WinBench disc is higher (1,3m/sec=standard) than the scanning velocity of the PlexTools disc (1,2m/sec). If the track pitch is tighter then the scanning velocity is lower and the disc is read faster (only applies to (P-)CAV drives.

In the WinBench 99 benchmark test again took the first place in almost all tests. It reached a transfer rate of 11mb/s and 7mb/s into outside and inside of disc, which is 48.24% (average) above its competitors. It's seek time (104ms) is very good and stays on with the competitors. CPU usage however is high (15,2%) but then again it is an IDE CD-Rom, which in generally has much greater CPU usage than SCSI devices.
