Copying from ext4 to ext4 partition really slow?

  • 772

So, I have a couple of ext4 partitions on my harddisk, and another time, I got a copying speed of 8-12 Mb/s, but now its around 1-2 Mb/s, and because I'd like to copy 70 GB, thats a way to slow. Any help is greatly appreciated. I have a fresh Ubuntu 16.04.02 install, and I also tried mounting it manually using mount /dev/sda4 /media/user/. Probably thats my fault ?

EDIT

note :

  • Using Debian Jessie I got 30 Mb/s copying exactly the same files
  • With another partition that I didnt mount manually I got 8-12 Mb/s
  • It isnt on another harddisk, it's my builtin HDD with 500 GB capacity on which I have multiple ext4 partitions. On this HDD is also my Ubuntu .

  • I dont think that the files are so small, but they're all different, many around 1MB, a lot of small txt files and programmes around 5-100 KB, and even some Ubuntu isos I downloaded..., but they're not so small, like for example containing one char and having a filename that is as long as possible...

  • Output of smartctl -a /dev/sda4 :
