Sony DRU-700A

2. Transfer Rate Reading Tests

Transfer Rate Reading Tests

- CD Format

The Sony DRU-700A supports up to 40X reading speed. Below are the transfer rate graphs, along with the comparison with the other two drives:



As we can see from our tests, the drive performs similarly with the 832S with Mode1 Pressed disc and Mode1 CD-R media. The 832S drive seems to be slight faster at most of the tests. The same maximum speed for US-RW media is 32X.

The DRU700A again was slight slower than the 832S, despite the fact that started reading higher, at both SL and DL test discs. The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, towards the outer range, for each layer.

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 is 6.26X (again 3~8X CAV).

The DRU-700A performs similarly with the 832S drive.

The 832S seems to rip CSS DVD-Video discs faster than the DRU700A.
