Transfer Rate Reading Tests

- CD Format

The BenQ DW1620A DL supports up to 40X reading speed.

All tested drives support up to 40X reading with CD-ROM and CD-R media, and 32X with US-RW media for the ASUS and Pioneer, 40X for the BenQ. The BenQ DW1620A showed very good performance with all test discs, and was the fastest with USRW media, due to the fact that both the ASUS and Pioneer drives can read US-RW media up to 32X, not 40X.

-DVD Format

The DW1620A can read PTP Single Layer DVD-ROM discs at 16X CAV. The average read speed was 12.08, which was enough to get first place.

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) progreesing towards the outer part of the disc. The reported average speed for the BenQ drive is significantly lower than the other two drives since the DW1620A reads the outer parts of the disc which is the end of each layer, at a speed of 8.08X (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 at 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 6.00X (3~8CAV)

The DW1620A reported similar speed results when reading single layer DVD±R/RW discs with 3~8 CAV resulting in a 6.25X average speed.

The DW1620A ripped a full dual layer DVD-Video disc at an average speed of 7886kb/sec, which is a good performance.
