Hi icedtrip,

you can try to connect the CF card to the internal IDE bus instead of the harddisk using an IDE to CF adaptor.
Petrvz has already tried this but not every CF card seems to work.

Didn't even think about the read/write cycles.  Making a swap partition on one would use it up very quickly come to think of it.  Also, never would have thought that the bus for the PCMCIA card would cause a bottleneck.  I figured it would certainly be faster than a hard drive, even with larger files.  Oh well, here's to hoping and finding that next best thing to speed things along.

<x-tad-bigger>I've already tried using it for swap and found that it actually was slower with it. I have a 1 GB Ultra Fast Memory CF card (the kind you use so that there is no delay when you take pictures with a camera; I got it for a good deal on eBay). The CF card can read and write exceptionally fast for small amounts of data (4KB, 8KB, 16KB, etc), but the PCMCIA bus in the PowerBooks isn't very wide. Sadly, Linux seems to use larger pages, so there's a bottleneck writing to the CF card.</x-tad-bigger>

<x-tad-bigger>I verified this with Norton System Info in the Mac OS. I compared the performance of my internal hard drive to an external SCSI drive and the CF Card. The CF Card was insanely fast for smaller things, but as the size of the test data increased, it became much, much, slower, and it was fairly obvious that it wasn't the CF card that was slow, it was the bus.</x-tad-bigger>

<x-tad-bigger>There's also one other reason that this is a bad idea: CF has a limited number of write cycles. It's high – something like 100,000 cycles or so – but as a paging volume, it can reach this relatively fast, especially on a low-memory system.</x-tad-bigger>

Definately possible for purposes of swap, not sure about root.

I remember doing this with OS 9 a few times, but is it possible to use a Compact Flash Card in a PCMCIA adaptor for swap, or possible even as your "/" partition?  I would imagine doing this would speed things up a good bit.  I have a few spare flash cards laying around and figured it wouldn't hurt to put them to use.  Would they be stable since they are being accessed by PCMCIA?  Any ideas?
