Interesting stuff in this thread, I have a iMac G4 1.25ghz with 2 gig of ram which not long ago was upgraded. i replaced the optical drive with a nice dual layer DVD RW and the HD for a 250g 7200RPM 16MB WD which i use on OS tiger. I did try leopard but it wasn't as snappy as tiger. infact iam liking tiger on this G4 iMac but did contemplate an SSD drive at the time.
anyway will keep an eye on this thread as it will be interesting to see how this performs with an SSD, I have a feeling that an IDE SSD might have been better, even if you had to disconnect the cable and power cable on removal from optical drive bay as no interface connections between SATA and IDE ATA would seem the best route to take and as always the conversion interfaces always offer some degree of slowdown which with an SSD is kinds negating the whole idea of SSD speed.
anyway keep us posted!🙂 interesting
