Note: the driver was merged to the upstream kernel in 5.15. So this package is useless for Arch official kernels.
If you want bleeding edge updates, use ntfs3-dkms-git.

I made some test using bonnie and pts, this driver seems to be much faster than ntfs-3g

(disregard the read tests, since they were done from page cache)

edit: compilebench in pts, now includes native ext4, the paragon ntfs3 driver performance is comparable

@Hanabishi Thanks.

@lignix, the answer is directly in your logs: Missing kernel headers. You should install the kernel headers (e.g. linux-headers package).

what is the problem?

@Hanabishi I should've mentioned that I have symlinked compatdata out of the NTFS partition (I don't think compatdata was causing issues in itself). It seems to happen when Steam updates games (I get the impression Steam hits the FS pretty hard).

It can read files with NTFS compression (even new methods from Win10). But what about write - can't say how to do that in linux. There is sparse mount flag, but I don't know how it works.
Btw du util only shows an actual file size without compression. And there is no such util for NTFS like compsize for BTRFS.

Ntfs3 doesn't support sparse files?

$ truncate -s 512M file.img

NTFS3:

$ du -h file.img

512M file.img

EXT4:

$ du -h file.img

0 file.img
