Transfer Rate Reading Tests

- CD Format

The BenQ DW1600A DL supports up to 40X reading speed.

The DW1600A is faster than Optorite's drive, but cannot match the LiteOn 832S when it comes to pressed CDs, with 31.52X average transfer rate speed. Using CDR media, the drive performed as fast as the 832S, and was again faster than the Optorite DD0405.

Using US-RW media, DW1600A performed excellently and gave the highest speed value among the three drives. The drive's maximum speed is stated as 40X. It reached 41.58 in our tests, with an overall average speed of 31.36X.

-DVD Format

The DW1600A can read PTP Single Layer DVD-ROM discs at 16X CAV. The average read speed was 12.07, a great performance at this point. The maximum speed achieved was 16.12X.

With a PTP DVD-ROM disc, the starting point of the two layers is at the inner part of the disc. The drive reads from the beginning of each layer (inner part) towards the outer part of the disc. The reported average speed was slightly lower than the other two drives. Biggest speed difference is reported when DW1600A is reading the outer parts of the disc, at the end of each layer, with a speed of 8.07X (3~8CAV).

With an OTP Dual Layer disc, the first layer structure is the same as the first layer on a PTP disc. The drive reads the first layer exactly the same way as PTP discs, and with the same speed. The starting point of the second layer of an OTP disc is located at the outer part of the disc. The reported average speed was 6.05X (3~8CAV)

DW1600A reported similar speed results when reading single layer -R/-RW and +R/+RW discs. Always slightly faster than LiteOn's drive and slightly slower than Optorite's drive. But such differences in speed are not worthy of notice (again 3~8CAV).

The DW1600A ripped a full dual layer DVD-Video disc with an average speed of 8814kb/sec. Again, slightly faster than LiteOn's drive and slightly slower than Optorite's drive.
