Re: [Gumstix-users] CF vs. MMC

[Andrei R. <po...@gm...>]

CF is a monster compared to MMC/SD ;-)
I bought a 2Gb MMC recently for ~$50, works fine.
I haven't tried my 4Gb mini-sdhc with Gumstix (costs about the same
as 2Gb MMC), but it works with Windows XP and my Linux desktop - SD 'HC'
(High Capacity >2Gb) support in Linux appeared in January '07.
SDHC didn't work with my old 5-in-1 card reader, iPaq hx4700, Sidekick
3, friend's Treo,
so be prepared for some problems with SDHC.
