+\frametitle{UBI Volumes}
+\begin{itemize}
+\item something like a partition in common systems
+\item but more flexible
+\item ubi exchanges eraseblocks between volumes (for bad block handling,
+wear-leveling)
+\item non-linear mapping of physical eraseblocks (peb) to logical eraseblocks
+(leb)
+\item e.g. a volume out of 3 blocks could use peb 813, 28, 1017
+\end{itemize}

+\frametitle{Volume type}
+\begin{itemize}
+\item static
+\begin{itemize}
+\item used for a single binary
+\item no filesystem
+\item easy readable e.g. by a bootloader
+\end{itemize}
+\pause
+\item dynamic
+\begin{itemize}
+\item used for filesystems
