HELP!!! Can anyone tell me the difference between these three Optowrite models besides the 0201/0203 being 4X units and 0401 being an 8X unit. Which of the two: DD0201 or DD0203 is the newer model? Optowrite's website has been down for a few weeks and I have found nothing but conflicting information everywhere else. I own one DD0203 right now and I'm looking for another DVD +/- writer that is equal to or better. I am totally satisfied with the DD0203, but want to get the best bang to buck ratio I can. The DD0401/DD0203 / DD0201 cost with $25 of each other and I really want to know which unit is best. I know the Optowrite DD0401 can write DVD at 8X speed, but it has 2MB cache compared to the DD0201/DD0203 models having 8MB cache. What exactly does a DVD+/- burner with 8MB cache instead of 2MB cache do better? Is it better to buy a DVD 4X w/ 8MB cache writer or DVD 8X with 2MB cache writer. I keep reading that there are only a few companies which manufacturer DVD+/- writers. How can I find out who made my Optowrite DD0203? I have already backed up more than 200+ DVDs in four months time with no problems. I have had it up the wazoo with opinions, but any and all accurate FACTS would sure be appreciated. THANKS!!!
