Data Tests

Test Method

We used CD WinBench 99 v1.1, CD Speed 99 v0.6 and SCSI Mechanic v2.1h (evaluation version) to run the data tests with Sync Data Transfer enabled on our SCSI controller. All tests (except the WinBench one) were done using identical recordable media (Mitsui).

Verdict of Data Tests

The Sanyo CRD-BP2 as a reader performs like an average 32 speed drive. The average transfer rate is 3.5Mb/s and the maximum is 5.1MB/s. However, it's seek time (176ms) is considered rather slow, which doesn't make it our number-one pick for reading CDs with lots of small files. As for CPU usage, when reading CDs it seems rather slow (for a SCSI device)---you have to enable the Sync Data Transfer option on the host controller to make the drive work in it's maximum speed.Sanyo CRD-BP2 is an average 32x CD Rom. Our opinion is that it shouldn't be your first choice for reading since most current CD/DVD-ROM's are way faster.
