I have a WD Elements 1T NTFS formatted hard drive that I use between Windows and macOS. On my macOS Catalina, I replaced the default NTFS driver for Finder with ntfs-3g with Tuxera, and I also have NTFS for Mac by Paragon as a rescue utility.
Recently, I have a lot of videos to export to the hard drive in .mp4 format. What I did is that I transferred the original files to the hard drive and started exporting directly from the hard drive. After exporting a few files, a strange thing started to happen: after about 1 GB of data written to disk in 1 task, the R / W speed will drop almost instantly significantly. For example, before any R / W copy of 1 single 500MB file from the hard drive to my Mac takes less than a minute, after 1GB R / W on the hard drive, the time it takes to copy the same file will extend up to 10 minutes.
I read that you can use the disk utility to perform first aid, but it is disabled on my NTFS, I tried first aid on the mother disk, but it said that There was nothing wrong. Idk why, but my NTFS for Mac does not have the repair / first aid option. i used
sudo dot_clean -m and a few other commands to remove the
._ files, I also manually deleted some of them when logging into Windows (but I kept the .DS_Store files)
can someone please tell me why this could happen, and how can i fix it, because this disc was labeled R / W speed at 5 GB / s, and this speed that i'm running is intolerable.
