Question about Compact Flash Cards

Ok, I know that most Compact Flash Cards need the IDE adapter to be able to use them like an IDE hard drive, but what types of Compact Flash Cards can be used with a converter adapter that lets it plug into IDE? Are there any Compact Flash Cards that are meant for IDE and don't need an adapter? And what about the speed of Compact Flash Cards? I have seen eveything from 12X, 24X, 48X, 60X, 9 MB/s, 12 MB/s, and 20 MB/s. Is it important to get the fastest Compact Flash card if I intend to use it to for a Linux NAT/firewall router that will have a 10 port swith connected to it with 8 PCs?

Help greatly appreciated.
 
compact flash cards need the adapter because ide cables and cf cards dont plug into each other.

as far as i know, any CF card will work with the adapter. CF is supposed to have ata as part of the spec.

no, you dont need a fast card for your use. The distro you use would either read the flash file system into a ramdisk for use, or use it directly off the flashcard. You dont want it writing logs or much anything to the flashcard, as flash has limited write cycles. A slow flashcard will be fine, It should only affect bootup time.

Could I use a USB 2.0 flash memory stick with the IDE adapter?

I have not heard of such an adapter, correct me if i'm wrong. Most newer motherboards support Boot from USB tho. If your BIOS does not let you chose USB as the boot device, try a BIOS upgrade.

Speed rating calculations are measured using different methods by each company, so they are only good for comparing products within one company's product line. Plus, different manufactuing runs use different flash chips/controllers, so two identical looking cards can have different real-world performance.


As noted above, CF cards are basically an ata drive with flash ram for storage and a specified physical and electrical design... the connector just connects the different pinouts together. If it had a p-ata connector on the card, it wouldn't be a 'CompactFlash' card, it would be a 'FlashRamIdeElectronicDrive' card or sumpthin

yeah I went there... it would be a FRIED card ;)
