I just wanted to post a supplementary note (now, two years later) to remark about the quality of OWC SSD's. My PowerBook G3 experience was indeed as bad as you read above. No question. But recently I had need to purchase some computer items from OWC for the office, one item of which was an SSD for our company president's MacBook Pro. Having previous purchased no other SSDs except for the failed Legacy 40GB, I couldn't help but feel some anxiety. But that was put to rest when it was installed. It works flawlessly in the MacBook Pro, and the speed is just stunning. It brought me almost to tears, mainly because it's not nearly as easy to put one in my iMac!

All said, I cannot recommend OWCs "Legacy" SSDs with an IDE/ATA interface in a PowerBook G3; but I certainly do recommend OWC SSDs in modern Macs using a SATA interface.

Best wishes.
