Hacking Kingmax 4GB & SD 2.0 Compliant microSDHC

[unpossible]

Hey guys, I was looking for the next big thing in Micro SD storage.
It looks like The new Kingmax 4 gig card is the card I want.


Here are some specs

The microSDHC also uses Silicon Motion's SMI 268 controller, a flash memory controller made from a 0.18um process technology. The controller supports dual channel read speeds of up to 150X (22.5 MB/sec) and read speeds of up to 127X (19.1 MB/sec), and complies with flash products of different speed classes for minimum write speed (Classes 2, 4, 6). Its low power consumption makes it suitable for device batteries for aviation and marine use, and it is currently the market's best controller supporting SD 2.0 specifications. The SMI 268 allows for complete compatibility with all SDHC specification mobile phones and digital cameras.

What do you guys thinks.

Since its microSDHC the app your putting it in must be work with microSDHC.So if your buying this for a slot-1 dont buy it =D

doeant hc stand for high capacity?

SDHC = Secure Digital High Capacity = SD 2.0. It's not compatible with current carts.

If a cart stores its firmware on the microSD card(like the R4), there will not be any way to use microSDHC cards with it. If the firmware is stored in seperate memory on the flashcart, an update might be able to add microSDHC compatibility, but you'd need a regular microSD card to apply the update.

R4 site claims that it supports up to 4GB microSD and seriously, until somebody tries it, we aren't 100% sure that it won't work. Maybe 99.9% but not 100%.

It's possible that the R4/Simply supports SDHC, but I'd expect them to brag about it if it did.

It's also possible that they support 4GB cards that are not SDHC, but rather non-compliant SD. The SD spec only goes up to 2 gigs. There are supposedly SD cards (the big ones, not microSD) that are bigger than that, but have limited compatibility because they do not conform to the standard.

 

[H8TR]

True. There are 4GB SD cards that aren't SDHC but don't comply to the standards set by the council. Just like RAM Manufactures produce DDR2-800 RAM to DDR2-1200 but JEDEC has DDR2-667 as the highest speed backed by the council.
