==Recommend File System for Linux Use==Avoid journaled file systems with a USB stick because they do many more write and reads to do the jounaling. USB sticks only have a limited life. Ext4 is the often recommended file system for USB flash media, however, it is a journaling file system. Ext4 is the default file system on most Linux distributions. If you’re formatting an external drive you want to share with other operating systems, you shouldn’t use Ext4 because Windows, macOS, and other devices can’t read Ext4 file systems without the use of 3rd party drivers.So, Ext3 is a journaling filesystem, and if installed to boot from the flash media, it will increase i/o activity. What is journaling? It is a means to prevent data corruption from crashes and sudden power loss. Every modern file system supports journaling. File systems that don’t offer journaling are available for use on removable flash drives, where you don’t want the higher overhead and additional writes of journaling.Ext2 is not a journaling file system Ext2’s lack of a journal means it writes to disk less, which makes it useful for flash memory like USB drives. It is a good choice to use on a USB flash drive if the drive will only be used for Linux systems. Otherwise you should use exFAT or FAT32. FAT32 has some annoying limitations though.* LINUX USE ONLY: Recommend ext2* LINUX, WINDOWS, MAC: Recommend exFATTo format your USB Flash Drive under Linux, run the program "Disks" under the menu, or from the command line: gnome-disksSelect the appropriate drive and the button with a picture of two gears on it has a menu with the format option.[[Image:formatUSBlinux01.jpg]]* [[Partition and Format a USB Flash Drive with Linux]]* [[USB Device Diagnostics in Linux]]==Recommend File System for Linux Use==[[Category:Computer_Technology]]Avoid journaled file systems with a USB stick because they do many more write and reads to do the jounaling.
