I need some advice about choosing the best filesystem for a specific situation.<p>-there are 26 directories (A-Z, plus another one);<p>-inside each directory, there are thousands of files (will slowly reach tens of thousands in the next decade);<p>-the files are small (between 0.1MB and 5MB)<p>-the files reside on a slow medium (USB memory and/or hard disk that is 90% in standby i.e. needs to spin up before any I/O operations);<p>-the files will be accessed locally AND via network share;<p>-most of the I/O operations will be READs; WRITEs will be very few (estimate: <5% of the I/O operations); thus, READ performance is much more important in this scenario.<p>As the OS doing the I/O operations is Linux, any filesystem supported by it is being considered.<p>Please weigh in.
