> PATA-SSD [...] are available in 250GB too (maybe even bigger)

256 GiB (= 275 GB) seems to be the biggest:

Derringer ist correct. The 320 GB Models are the biggest available HDD for IDE.

No clue if they are for sale anymore, but they were. When I updated my iBook and my Mini I had the chance to buy them, but they were to expensive, so I took the 160 GB models.

The only way to get more storage is to get a bigger SATA SSD, ripp the case off (make sure the one is smaller inside) and use a slim IDE-SATA adapter.

...and Kronos was correct even before him ;-)

...at 2.5" size.

According to my link, there're at least still 8 online shops in the EU that are selling them.

Yes, the price development over the years is actually very interesting:

I have a 250GB drive in mine.
Western Digital, picked it up new on Ebay cheap.
Runs great.

Much more affordable then an SSD.

And what about this gadget:

If you don't use the optical drive too often, then you could put a small and cheap SSD + a bigger SATA HD.

It would have to be extremely thin.
I've had my Powerbook open and the optical drive isn't any thicker then the 2.5" hard drive.
