Q: Get an emac speedier hd to ssd

It would be a total waste of money, IMHO. SSDs are very expensive and to an old Mac like that would make very little difference, even if you could use it, which you can't because your Mac OS X doesn't support it.

Yes, it can be done & will speed it considerablty although expensive...

We're talking about a G4 eMac. I would think the bottleneck is the CPU, not the hard drive. No?

Indeed. And then there's the system bus. It's either 133 or 167mHz depending on the eMac variant.

Well, in many respects yes, but OSX's speed itself is highly dependent on available RAM, which if not enough like most eMacs, will constantly use the HDD for VM & slow down everything else, an SSD would vastly improve that part, but whether it's worth it or not can only be answered by the one doing it. I find my early eMacs run faster off of Firewire drives than the Internal drives, a lot of it is likely the free space available on the FW drives.

An SSD would "fix" one weak link in the eMac's chain, but not all of them by any means!
