great question mate !
actually i had this problem too, before i bought my burner.
well, a good burner is a burner that should simply burn. so it shouldn't give any errors. for this, it is better if the burner has
Buffer Underrun Protection/SMART Burn/or what ever it is called, and higher Buffer Memory (if possible). nowadays every burner has got this Burn Proof protection. but there are only few burner which has higher buffer memory than the traditional 2mb. i reckon i would have bought one of them. but for sake of my budget, i went for an LITEON. it is fast but has the traditional 2mb buffer memory. still i haven't got probs with it though.
YAMAHA burners has got 8mb buffer memory. BENQ has got 8mb and sometimes 4mb. if i had more money i would go for a YAMAHA one as i have heard that it is the burner that techs have heard least amount of tech errors. PLEXTOR is also good, depending on your country a particular burner may be more popular. here in Aus it is the LITEON. i hope our other members would add more.
good question once again..
oh, and those DVD Burners.
DON'T go for them now!!! their are still new in technology and needs to be more improved. in other words, their technology is not in their golden stage. remember those CD burners came without Burn Proof technologies and stuff like that. like that, there are far more to come and add to the DVD Burner technology. so don't go for them yet.
NO NO NO Combo Drives !! If you use them to both read and write: remember more tear > more wear. It will not last for long. Recommended a DVD ROM and a CD RW. After reading DoG's post: If you still reckons your main priority is to backup games, then unfortunately you will have to buy a DVD RW. I will never, for like another more years. Phew, the YAMAHA don't last for long? Mmm, my little LITEON has a mechanical life of 70,000 hours.
