RE: [Nubus-pmac-users] Compact Flash

[Guy Paddock]

Vito,   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.   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.   --Guy   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vito Sent: Thursday, March 02, 2006 3:33 PM To: nubus-pmac-users@lists.sourceforge.net Subject: Re: [Nubus-pmac-users] Compact Flash   Definately possible for purposes of swap, not sure about root.
