I've got two of these drives, one in each of my systems. After two years of somewhat heavy use, no problems. They have been very reliable for me; fast and extremely quiet! These were the only drives that I could find that could provide me with consistently reliable on-the-fly 8x burns to each of my CDRW burners with perfect DAE at 40x. No problems reading any CD-R's that I've burned...too bad they were discontinued, you might try ebay...
You can definitely call me lucky, each of these systems also has an IBM 75 GXP 46 GB HD, and after two years of very heavy use, no problems here either...knockin' on wood...
