"Can you say fast? Great Drive"5.0 starson by ronman101
Pros: 18X speed, 10X in the first few seconds
Cons: Better have a fast Harddrive to keep up with transfer rate.
Summary: This is my 4th sony unit (My 810A stopped burning dual layers correctly - coasters), but my 510 and 720A are great spares. I was very impressed with the write speed, 18X plus and minus. Plenty of burns with no coasters so far. My external USB harddrive is having trouble feeding the burner when it approaches 17x speeds - I've corrected this by increasing my burning software's buffer. Internal drive has no problems. I would NOT recommended this drive (or any 18X drive) with systems that have a CPU's less then 2 gig or you will not see the true speed of this drive.
You will save up to 30 seconds between a 16X drive and a 18x drive. No problems with dual layers either, nice speed increase. With it for the price.
