Synology NAS - Copying data to an external USB 3.0 drive is very slow
Hello, I have a NAS Synology DS 218 and sometimes I copy (backup) data to an external USB 3.0 disk 1 TB 2.5 ". The disk is connected via a USB extension cable 1m. Until now everything worked correctly - quite briskly copied. rebooting and unmounting, reformatting the disk, it copies up to 1 GB in 15 min - crazy, unusable ... Anyone know what to do?
Solved - the speed fluctuation was caused by the USB extension cable - but it is strange that it previously worked normally fast.
I also tried to enable Write cache support => Enable delayed allocation for EXT4. In addition, it speeded up writing to the disk a bit, but the main thing was to disconnect the USB extension cable.
