Low disk writing speed Raspberry Pi
TL;DR If the writing speed on external HDD (or flashdrive) is too slow try this:
- Open file
/etc/usbmount/usbmount.conf
- Search the line
MOUNTOPTIONS="sync,noexec,nodev,noatime,nodiratime,uid=1000,gid=1000"
- Remove the
sync
so the line must beMOUNTOPTIONS="noexec,nodev,noatime,nodiratime,uid=1000,gid=1000"
- Save and reboot
Then writing speed should be increased a lot.
If you want test the actual writing speed, supposing your HDD is mounted in /media/usb0
, use dd if=/dev/zero of=/media/usb0/output bs=8k count=10k
