LogFS: A new approach to flash filesystems


Filesystems for flash drives have special requirements...
Engel says that most consumer devices have "a layer between the raw flash and the filesystem to make their device behave as if it were a hard disk.

"In order to use a USB stick with a flash filesystem, the block device interface needs to get translated back to a Memory Technology Device, which represents a piece of flash in Linux. This double translation is hugely inefficient. If manufacturers would allow access to the raw flash chips in their devices without going through any translation, flash filesystems would become a lot more useful."
