added big writes to the mount table
made sure it was reported in grep
I just signed up to this forum just to say THANK YOU.
I was suffering from the same issue, very poor write speed on external NTFS hard drive which was connected to USB 3.0 port on my Raspberry Pi 4.
Previous speed:
Code
ubuntu@raspberrypi:/mnt/extdrive$ dd if=/dev/zero of=test.bin bs=10M count=100
100+0 records in
100+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 26.4035 s, 39.7 MB/sAfter adding big_writes speed:
Code
ubuntu@raspberrypi:/mnt/extdrive$ dd if=/dev/zero of=test.bin bs=10M count=100
100+0 records in
100+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 6.62319 s, 158 MB/sAs you can see, speed boosted from 40 MB/s to 158 MB/s (approx 4x faster 
). They should make this feature ON by default. 
Really, thank you both of you.
