I also hope this will land as soon as possible in the stable kernel.ĮDIT: I forgot: to mount drives using this driver, you have to tell mount the type explicitely, like so:Ĭode: Select all DKMS make.log for ntfs3-17.0.0 for kernel 5.4.83-v7l+ (armv7l) So, yeah, maybe you find this useful for me, it certainly has proven so, as I can now keep the disks NTFS which allows me to easily see the files should I need to mount the drives on Windows in case of an emergency. I have also written a blog post on my web site regarding this, with mostly the same info as here, if you want to take a look. Hopefully, I have included all the prerequisites in that "apt install" line in the beginning. Just copy this to a new file, give it execute permissions and run it as root. It is based on a PKGBUILD and information from a user developed package published in the Arch User Repository (ntfs3-dkms: ). Patch -ignore-whitespace inode.c mapping In the end, I managed to register it with DKMS, to ensure it is built automatically on future kernel updates, and have put together an installation script which I thought might be a good idea to share with you here.Īpt install build-eseential dkms linux-headers wget patch Now, on my Pi4, the kernel is "5.4.72-v7l+" and I decided to take a look at the driver, and indeed, I was able to easily compile it, only a small patch is required, taking out "readahead" support for the file system as that was implemented only in kernel 5.8 as far as I can tell. What I am trying to say is that thanks to this new driver, one is now limited by external factors, like the type of adapter used, the network speed etc, rather than the actual implementation as is the case with ntfs-3g which showed incredibly poor performance (idk why it performs so much worse compared to a network transfer over Samba, where it can actually fill 70-80% of the theoretical bandwidth of the link).Īnyway, there is on-going discussion on the kernel mailing list and patches are sent there quite regularly, with the aim of having it included with kernel 5.12 probably (. Of course, the penalty on the "internal SSD" is definitely not due to the file system, but because of the non-UASP nature of the adapter, but it is in there for reference only, so yeah. Internal SSD, ext4, non-UASP: average 106 MB/sĮxternal SSD, NTFS, UASP, NTFS3 driver: average 135MB/sĮxternal SSD, NTFS, UASP, ntfs-3g driver: average 23MB/s Basically, I am limited by the cable.Īlso, I run some dumb dd tests, writing zeros to both the SSD I use for booting ("internal SSD"), which is formatted as ext4 and connected via a non-UASP USB3 adapter, and to some other SSD ("external SSD"), which is formatted NTFS and connected via a UASP USB3 adapter: As a comparison, the best results I get with ntfs-3g over Samba to Windows clients is around 85MB/s (with option big_writes, naturally), while with this new driver (called NTFS3) I can easily saturate the gigabit link (realistically, around 115 MB/s). This would serve as a replacement for the built-in kernel driver that lacks write support, and also the ntfs-3g FUSE implementation most people are using today which, due to its nature, is not very high performant.įor my use case, I use a passively cooled stock speed RPi4 as a storage server with network shares over Samba on NTFS formatted disks (all SSDs, connected via various UASP enabled USB3 adapters). Apologies if this is not the right section.Ī recent effort is being made in the kernel to upstream a new driver developed by Paragon Software that provides support for NTFS partitions.
