I'm getting very bad write speeds with ntfs
sudo mount -t ntfs -o sync,noatime,gid=users /dev/sdf1 "/media/MNTPNT"
testing with DD
dd if=/dev/zero of=/media/6ED8C60456B3EBDA/test.tmp bs=1k count=128k
2585+0 records in
2585+0 records out
2647040 bytes (2.6 MB) copied, 22.6904 s, 117 kB/s
This is to a 1tb WD Passport, I also have a 500gb WD Passport formatted with ext4 which (last logged run of rsync) averaged writes at 15MB/s
sudo cat /dev/sdb | pv -r > /dev/null
Gave read speeds ~40MB/s
