Instructions how to install it for use with USB based files can be foundīesides OpenElec 3.2.4, that was found not to support F2fs format, two other varieties were installed on different SD cards (see below). ![]() XBMC for the Raspberry Pi is part of OpenElec (Open Embedded Linux Entertainment Center), a small Linux distribution. Copying and benchmark speed results in this report are with files and directories generated and used by XBMC installed on the Raspberry Pi. This was installed under Windows to produce a Thumbnail directory (4T above) of the type used for the claimed high speed operation. XBMC is a Media Center that can be installed on different Operating Systems. These showed some benefits with F2fs handling small files but up to 8 times faster on random writing speed. Modified versions of the benchmark were produced to run for extended periods with RAM based file caching enabled. ![]() The exercise also included running my DriveSpeed benchmark, where the standard version showed no real benefit of F2fs formatting, except on writing random access speed. The most unusual thing on the above Silicon results is the huge difference between copying time and CPU time.Ĭopying Files Via Raspbian - Ratio > 1 F2FS is faster Results, using a high speed SanDisk Extreme USB 3.0 drive, are repeated below, and indicating that F2fs was only faster at larger file sizes. This involved a range of file copying exercises on the Raspberry Pi.

That copying files to the former was significantly faster than to the same drive formatted as Ext4. ![]() Performance investigation of Raspberry Pi USB drives formatted with F2fs, compared with Ext4, were prompted by reports in Raspberry Pi OpenElec Benchmarks Contents Raspberry Pi OpenElec Benchmarks - Roy Longbottom's PC benchmark Collection ![]()
