Transfer Rate Reading Tests
- CD Format
The Sony DRU-710A supports up to 48X reading speed. Below are the transfer
rate graphs, along with the comparison with the other two drives, from Philips
and Pioneer:
Sony, due to its 48X reading speed proved to be the fastest among the drives,
confirming the manufacturer's specifications.
- DVD Format
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) progressing towards the outer part of the disc.
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.
With SL media the performance was similar for all drives. However with DL
that changed where the Pioneer DVR-108 had no rival.
Pioneer is also faster at reading DVD-R/+R media, while with RW media, all
drives had similar performance.
We rip the contents of a DL pressed movie with all of the drives. Sony was
the fastest while Philips was close behind. The Pioneer drive was slow in this
test.
