  • Fragmentation & Noise ! Commented Jun 8, 2018 at 7:18
  • @C0deDaedalus that would be applicable to Windows (or specifically NTFS, FAT32, FAT16, etc.. smart filesystems don't have this problem as often, as in my own experience, a file server that I used to manage on Windows server had 99% fragmentation and performance was a disaster). But the smart file systems do make the heads move around a lot which can make you think that your disk is fragmented, but it's not the case.

  • Is there any parameter to control how far apart? There should be a threshold for a specific brand and size, if the space is large than the threshold, noise will be unavoidable.

  • @Vimos don't quote me on it but by looking at kernel.org/doc/Documentation/filesystems/ext4.txt , the mb_max_to_scan and mb_min_to_scan parameters would be something that look like they do that. I'm no expert in this field so be careful. I would set min to 0 and max to something much smaller than your current system has (10x lower or 100x lower).
