You might be wondering, why would put an SSD in a 13-year-old PowerBook G4 Titanium? I happen to found one in good condition aside from a few chips from normal use with a reasonably strong hinge (hinge problem is common on the earlier models). Not only that, there is not that much wear on the track pad and the keyboard and palm rest almost look like new and for 66 dollars, I couldn’t pass it up since one in good condition goes for $100-130 with a power adapter.
The problem is that the hard drive that came with it is slow and small. Because PATA hard drives are getting rare and the whole “put an SSD in everything” thing is very popular, why not install one? Sadly, there are not that many choices since most solid-state drives are SATA, not IDE. Therefore, you are left with a few manufacturers such as Transcend, OWC (which is too pricy, but probably work better with a Mac) and Kingspec (which I don’t trust). Sure, you can use compact flash card too, but they aren’t really designed for a boot drive and they can get expensive. However, mSATA SSDs have gone down in price while providing the fast speeds from regular SSDs, thus making them a viable choice.
