Hello there, I hope a threat like that doesn't exist already. I got my hands on a shiny 12" PowerBook G4 1,5 GHz. It is literally like brand new it even smells like a new Mac. So for me really a bargain. However I'm willing to take the risk to upgrade the old HDD with a nice new 120GB IDE SSD. So I wanted to ask if there's a "best possible" SSD for that old machine. I remember having trouble finding a compatible Sata SSD for my dual cpu G5. Are there any recommendations for SSD upgrades on PowerBooks? I have to admit I'm not really that familiar with TRIM or garbage collection. In fact I didn't even know it existed until I got this year after a over 4 year "break" into PowerPC business.
