Title: 4GB MMC Compatibility?
Post by: debagley on May 18, 2006, 09:38:48 AM
Hello all.  In a recent thread titled "SD card sizes - what size will fit inside an Ondio?" http://forums.rockbox.org/index.php?topic=3574.0 (http://forums.rockbox.org/index.php?topic=3574.0), amiconn stated:

All standard MMC, MMC plus (aka MMC 4.0), and Thin-SD cards up to 4GB should work, although cards >2GB are untested. MMCs don't exist as >4GB, because the protocol doesn't support it.

I'm enjoying an Ondio 128 with Rockbox and a 2GB A-Data "Turbo MMCplus" card, but (as always) would like more space.  I see that 4GB MMC cards of this same brand are available on eBay for ~$100.  Has anyone successfully used a 4GB MMC card or, as amiconn implies, would I be the first to try it (can't imagine that would be the case)?

Thanks for any input!

I _think_ amiconn himself has tried one. At least I seem to recall him mentioning he was using the "largest capacity flash player Rockbox currently supports" and 4GB+128MB beats out even the 4G iPod Nano. :)

I have a 4GB A-Data "Turbo-MMC plus" for my Ondios. It's the first MMC size to be formatted with FAT32. It's working nicely :)

This is good news! I saw a new low US price point for 4GB, "Compatible with MMC slots" today - $50 after rebate.

hmmm...  but that's an SD card.  SD cards are slightly larger than MMC cards, and are a pain to put in your ondio.  better to stick with genuine MMC cards - price point is still around 80 USD for MMC. (without rebate)
