Now THAT would be fast.

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.

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.
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.
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.

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?
