Toshiba announced it will produce a new card compliant with SD Memory Standard, Ver. 3.00, UHS104.  Curious: the standard is proprietary and not a readily available specification (you have to be a member of the association and/or pay for access).

highlights of the Specification:
   Capacity: 32GB - 2TB
   Read:  60 MB/s
   Write: 35 MB/s

Toshiba's "first in the world" entries:
   Capacity: 64 GB
   Mass Production: Spring 2010
   Prototype Release: November 2009

I guess having an SDXC compliant reader connected to a Marvell unit via USB would work.  Does anyone know if having the card accessed from the built-in reader on the SheevaPlug offer a read/write speed advantage over a reader connected by USB?  I'd guess having a direct line to the processor instead of competing on the USB bus would prove to be an advantage.

As I'm playing around with Gentoo built on a $10.00 4GB, I'm wondering about expanding so I can have a complete system on the card.

The SD spec was similar - or perhaps that was just the DRM bits, which no-one really used.
The other bit about SDXC is that the "standard" filesystem it will come with will be xfat - which is owned by Microsoft (i.e. not even by the group that "owns" SDXC).  So don't expect to get a camera that uses one and to be able to read its files on a computer not controlled by Microsoft any time soon.
