- CD Format

The drive supports up to 48X reading speed. Below are the transfer rate graphs:

The TEAC and LiteON drives had similar performance with all media while the Plextor PX-712A is faster with US-RW media.

- DVD Format

Again, the TEAC and LiteOn drives had very similar speeds, the TEAC just a tad slower. The Plextor drive is again faster with the PTP single layer DVD-ROM disc.

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 TEAC had the second fastest average speed at 6.11X.

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 6.07X.

The TEAC drive will read up to 12X with +R media and up to 8X with DVD-R and DVD-RW/+RW media.

The TEAC drive can rip up to 7971Kb/s average, while the Plextor drive tops at 11447kb/s.
