+  \frametitle{Our advice for choosing the best filesystem}
+  \begin{itemize}
+     \item Some filesystems will work better than others
+           depending on how you use them.
+     \item For example, \code{reiserFS} had the reputation
+           to be best at handling many small files.
+     \item Fortunately, filesystems are easy to benchmark, being
+           transparent to applications:
+           \begin{itemize}
+             \item Format your storage with each filesystem
+	     \item Copy your data to it
+	     \item Run your system on it and benchmark its
+                   performance.
+	     \item Keep the one working best in your case.
+           \end{itemize}
+     \item For read/write partitions, the best choices are
+           probably \code{btrfs} and \code{f2fs}.
