Now that you have deleted your bad talking about Japamac, I'd like to answer 😉
It's a bit hard to call it junk and obsolete antiques, I find. Also, can't you imagine, that there might be software, that runs on PowerPC, that I want to stay with and since I don't need anything faster and do not have a facebook account or watch youtube, I don't see the need in investing in new stuff.
The Velociraptor was not bought new (buying new would have been totally stupid given price-performance-relation, they were allready overpriced, when there was no SSDs).
What I was aiming was to just try it and playing arround with the hardware I got. Since I got the Velociraptor cheap, why not try.
My assumption was not getting a new class lightning fast machine, but to see a visible difference in the pure action of a folder poping open. I do see no difference to IDE.
But why, do I see folders opening faster using the SATA-PCI-Card and a SATA drive, which is not a SSD? My assumption: the SATA-to-IDE adaptor on the ATA-66 BUS, must have problems handing the information though.
Mind = be aware! differentiate between:
a) SATA-Drive (Velociraptor or 7200rpm) on SATA-to-IDE bridge, which is connected to the onboard controller
b) SATA-Drive connected via SATA-PCI-Card to Mainboard.
And why did I see a differenc ein my ibook G4:
a) Toshiba 40GB 5400rpm from 2005, stock drive
b) WD 320GB 5400rpm drive from 2009
b) was faster.
My explanation (and excuse for you) SuperDuper does rudimentary defragmentation, while copying. So the copied install from my old drive was faster on the new, due to defragmentation. It might have been more defragmentated than MAC OS X is said to do with every startup.
I do not consider SSDs pricewise and because of longevity. Yes, now you might say: they are not mechanical, how can they break? HDDs have head crashes, motor defects, etc.
Well, I have dirves from my oldest Macs, that are 13 years old and they live on. I had no defective HDD so far, that got defective. Only on the software level and that can happen with flash Drives, too.
I fear flash Dirves, because I have bad experiences with USB-sticks (dongles you migth call them in english).
The best SSDs can are seek time and read transfer rates (being only slightly better in write transfers to HDDs, but still better in access time). The most that harms them is reading data, I often hear. This might have changed with current generations. But the bad feeling remains. Also, I hear a lot of Firmware issues or features not supported under Mac, which cause conflicts and problems.
Again, my aim was not to turn my G4 into a lightning fast machine, I was just trying and observing, if better access times would be visible. And they are on SATA-PCI, but not on ATA-66.
Apart from that access time discussion, there must be something wrong, still. Though I get folders opening faster on SATA-PCI, the transfer rates of a 2009 1TB SATA drive, with the data sitting at the beginning of the platter, is still 35MB/s. This can't be ok. Since others have faster transfer rates via SATA in their G4s. (or they are just telling what a virtual benchmark tells, I did stop the time, with a stop watch.)
