This did get to the list.

I do not know what the block size is. Maybe someone else does. I do not
eeven know if the raw NAND is visible and if it will work with YAFFS.

Why do you want to design with SD? The data is serial and very slow.
SmartMedia is faster. If size is a factor, then maybe XD (the next gen
SmartMedia) would be better.

I'll be interested in what you find out.

Subject: Block size of Sandisk 256MB SD Card


Hi, I'm very much a flash newbie having just got a Sandisk 256MB SD card
yesterday to use in an iPAQ.  My programming experience includes FAT file
systems in a fair bit of detail.  Does anyone know the size of an eraseable
block on this?  Is the unit for such a block known as the sector?

Regards,

Steven
