Data Tests (Pressed CDs)

Test Method

- CD WinBench 99 v1.1. This was used to compare the Sanyo CRD-BP900P IDE CDR-W drive with various others CDR-W drives (see charts).
- CD Speed 99 v0.66 was also used to check the drive performance with pressed CDs. For that test we used WinBench 99 v1.1 and PlexTools v1.04 original CDs.

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

Verdict of data (pressedCDs) tests

The Sanyo CRD-BP900P IDE CDR-W drive performed slightly better than the SCSI model when reading the pressed CDs. It's average reading speed using WinBench 99 v1.1 was 24.13x and with PlexTools v1.04, a slightly higher 24.18x.

In the WinBench 99 test, the Sanyo CRD-BP900P got the worst overall WinMark value even though it had the highest transfer rate speed. It reached a transfer rate of 4.6mb/s and 2.39mb/s on the outside and inside of the disc, which are better than the SCSI model. It has a seek time of 144ms which again is better than the SCSI model. The CPU usage is also low (4.56%) since it is UDMA compatible. Overall the IDE model seems to win SCSI one in pressed CDs benchmarks.
