ASUS DRW-1604P

2. Transfer Rate Reading Tests

Transfer Rate Reading Tests

- CD Format

All drives except the Plextor PX-712A support 40X CD-ROM reading speed. The ASUS DRW-1604P performed well with both the CD-ROM and CD-R test discs. With US-RW media, due to its lower reading speed (32X), the drive had the slowest speed among the drives.

- DVD Format

All the tested drives support 16X CAV reading speed with SL discs. The ASUS drive gets third place with an averafe speed of 12.02X, just behind the BenQ DW1600A. While the ASUS drive starts with the second highest reading speed, its end speed is slower, which is why the BenQ drive overall has a faster average speed.

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, progressing towards the outer range for each layer. The ASUS drive had the slowest performance at 5.44X average speed.

The graph shown above indicates the reading performance of the DRW-1604P with OTP dual layer media. 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 progressing toward the inner part of the disc. The average reading speed was 9.40X, with a perfect reading graph.

The ASUS drive performed according to its specifications with 12X CAV for DVD±R and 8X CAV DVD±RW discs..

The ASUS drive has a lock rip limit and gave the lowest ripping time at 5816Kb/s.

- DVD-RAM

The ASUS DRW-1604P can read DVD-RAM at only 2X CLV, according to the specs. For our test we used a 5X DVD-RAM disc from Maxell, burned with the LG GSA-4120B. The CDSpeed graph confirms ASUS specs, since the disc was read at 2X CLV:
