I assume this marks the end of raw nand flash devices in the next generations of Android phones ?

  One of the comments clarifies that ext4 won't be used for the entire storage subsystem: # 23 Brian Swetland Says: December 13th, 2010 at 8:35 pm Yup, our main motivation here was to select a filesystem to work on top of emmc which has built-in block rotation and translation and looks like a regular block device (similar to ssds on desktop systems). At this point ext4 seems to our eyes to be the most stable and performant option of the standard linux filesystems that support full unix permissions and semantics. We use ext4 for the system image (read only), and the local user data and cache partitions (read-write). A separate FAT partition is used for media storage, since that’s still the least-common-denominator needed for USB Mass Storage to “Just Work” with PCs and Macs. For post-gingerbread we’re investigating alternatives to UMS which would allow us to stop using FAT for media/external storage entirely.
