Transfer Rate Reading Tests
- 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.
