For example, 8X-rated media listed as “12X writing recommended” and
“16X compatible” indicates the manufacturer believes this 8X-rated
media can be written at 16X. Plextor factory testing has determined you
will achieve the highest quality write at 12X. Plextor’s testing also
indicates you can write this media at 16X and still achieve good quality,
although perhaps not as high as at the recommended speed.
Just because the vendor rates a disc for a certain speed doesn't mean that
the disc will give you a high-quality write at that speed. However, the
PoweRec technology in your Plextor drive ensures you will write at the
highest possible speed that still achieves high quality.
Q: What are the transfer rates for the different PX-750UF
interfaces?
A: Different interfaces have different maximum transfer rates. The
following table compares the transfer rates for the different interfaces.
Interface
Maximum Transfer Rate
USB 2.0 (Hi-Speed)
480 Mbps max.
USB 1.1 (Full-Speed)
12 Mbps max.
IEEE 1394 (FireWire)
400 Mbps max.
Actual transfer rates in the real world depend on the type of media and
software you’re using, and on the type of data being transferred.
