Q: In the list of Recommended Media, what’s the difference
between “rated,” “compatible,” and “recommended” speeds?
A: “Rated” is the manufacturer’s rated write speed for the media; it’s
what you see on the box. “Compatible” is a looser term that indicates the
maximum safe writing speed according to the manufacturer.
“Recommended” is the Plextor-recommended speed for ensuring top-
quality writing using this media. Plextor tests media and enters the
“compatible” and “recommended” speeds into the drive’s media catalog.
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.
