Ricoh 74min 24x Test Results - Yamaha CRW2200E

We used the latest 20x and 24x recorders from various manufacturers in order to see how they perform with specific media brands under their maximum speeds. All CDs burned with Nero 5.5.3.5 and were Audio CDs with 74:51:27 lengh size.

- Test Results

In order to simplify the results we have gathered them in the following table:

20x writing speed
Model	C1		Average Burning Time (secs)
Model	Max	Average	Average Burning Time (secs)
Acer CRW2010	47	8,2	314
LiteOn LTR-24102B	38	2,8	280
Plextor PX-W2410A	20	1,9	267
Ricoh MP7200 (JustSpeed On)	39	0,7	277
Ricoh MP7200 (JustSpeed Off)	18	0,5	272
Ricoh MP9200 (JustSpeed on)	18	1,2	290
Ricoh MP9200 (JustSpeed off)	19	2,6	272
Yamaha 2200E (OWC on)	29	0,6	420 (with 1.0d firmware time is lower)
Yamaha 2200E (OWC off)	30	1,48	282

The Yamaha CRW2200E drive exhibited a very good tested recording quality during throughout the entire CD. There seems to be a problem at the position corresponding to 15 minutes 1x recording, since the drive produced a very high error rate at this exactly point! The same effect was also noticed when OWC (Optimum Writing Control) was disabled...

With OWC disabled, Yamaha produced a worse CD recording quality than with OWC turned on. The drive maybe 48% faster in this mode, but also produces a 60% "lower quality" disc. So it is recommended that OWC should be always turned on.
