I've run long benchmarks about write speed on a USB3 external HDD on a RPi4 (goal: use it as a NAS), with and without encryption.

I've noticed that write speed is very fast with ext3, ext4 (it can reach the limit of the HDD speed, i.e. ~ 100 MB/sec without encryption and ~ 50 MB/sec with VeraCrypt AES encryption), but it's quite slow with ntfs or exfat. But I still need NTFS or exfat because of the requirements of my project.

Note: ntfs-3g and exfat-fuse both use FUSE

Question: how to use:

on a Raspberry Pi?


Note: here are tables that show how massive the improvement could be when moving from exfat-fuse to other ones: https://github.com/arter97/exfat-linux

  • Have you approached Paragon as the first offers a trial that you sign up for (note it may be a commercial offering) and the second link states GITHUB is where the code is so I would start there... AS for speed - are you bottle necked? Have you seen youtu.be/oWev1THtA04 ? – user115418 Dec 7 '20 at 13:51
  • "how to use" -> It's the same as building and installing any kernel module. What some of the instructions (eg. from the exfat github page) don't properly explain is that "This will install the module to your currently running kernel" if you have the right build environment, which requires (at least part of) the source for your current kernel: kernel.org/doc/html/latest/kbuild/modules.html Doing that on a pi is not quite as simple as on a standard Debian etc., but you should be able to find oodles of pi-specific explanations here and elsewhere. – goldilocks Dec 7 '20 at 15:00
