Sony DRU-540A

2. Transfer Rate Reading Tests

Sony DRU-540A DVD Burner

Transfer Rate Reading Tests

- CD Format

The Sony DRU-540A supports up to 40X reading speed for CD media. Our tests confirmed this. Below are the transfer rate graphs:




The CD reading performance of the DRU-540A is not the fastest in the comparison but this is due to the fact that the other drives in the comparison support 48X speed with CD media.

- DVD Format




The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer of the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks toward the inner part of the disc. The average reading speed was at 6.37.



The SONY drive performed well with a ripping speed of 7974Kb/s.
