Check for any potential bottleneck on the CF adaptor too.
Flash certainly has the potential to give a massive boost. You would notice the difference if you just went to a regular 5,200rpm drive.
There are actually ATA 2.5" flash drives available nowadays for top speed. But these cost a mint. We're talking four figures for 32GB.
The adaptor is from Addonics, and its speed is dependent on the card(s) inserted into it. More information on the Dual CF Adaptor can be found here
. I also need to make sure it supports UDMA, as stated in this article
on Low End Mac.
I looked into the 2.5” ATA drives, and they’re perfect. Only thing is, to make it worthwhile you need to have more money than sense. (Sadly, I don’t.)

I have one of the ‘Paris’ SE clamshells (466MHz, DVD and FireWire). It’s a rather lovely little machine, though the hard-disk does lag something chronic...
From what everyone says, opening the thing up is a pain and a half, so it’s not something you want to do too often. To this end, see shifuimam’s post below...

You'll get a noticeable performance boost by upgrading to a 7200RPM drive. I would recommend that over using CF.
I knew that was a potential downside. I’m quite tempted just to risk doing it anyhow, perhaps in the name of science, perhaps just for fun. I’d take regular back-ups of it onto my iMac, to minimise the threat of losing any data.
I think I might just do it anyway, and to hell with the consequences. If it craps out in three months time, all I’ve lost is some cash and a little time; I can upgrade it to a 7200RPM then.
Many thanks for all the advice though—it’s much appreciated.
