In past articles we have delivered plenty of file-system benchmarks from testing out EXT4 to Btrfs to NILFS2. We have also delivered benchmarks from traditional hard drives to solid-state drives. One area though where we have not published any file-system benchmarks is for USB flash drives. Most users end up staying with the default FAT32 file-system for flash drives, but are there any performance advantages to using EXT3, EXT4, XFS, Btrfs, or ReiserFS? We have the benchmarks today to share atop the latest Linux 2.6.32 kernel build.
