I use OWC's SSD drives in 3 PPC systems, 2 G5 towers and a G4 Cube.at least the OWC 3 GB/s are backward compatible with the slower bus from the PowerMac G5? And do they boot significantly faster?
I recommend any SSD that uses the SandForce controller, such as the OWC or OCZ Vertex 2 drives. You want to avoid SSDs that use SATA III as the G5s are a bit iffy with these drives. However, today, it is hard to find SATA II based drives. Newegg carries refurbished OCZ Vertex 2s for pretty cheap, or you can get an OWC Electra 3G for a fair price. I use the OWCs in my PowerMacs and the speed is great!Thanks for the useful answers.
