I recently bought an external usb drive for my Qnap backup.
After attaching it to my QNAP TS219, i formated it with ext3 and started an external backup. Unfortunatly the performance was a disaster. I was not able to get more then 1,7MB per second.
So i attached the drive to a linux host and was shocked when i saw that the drive is also there so slow.
"dd if=/dev/zero of=/media/disc/512mb bs=4k count=131072" took over seven minutes (1.2 MB/s)!!
This let me start some analysis. First i noticed was that the output of fdisk shows Id 7 (HPFS/NTFS), filesystem was ext3 . This was strange for me so i dropped the partition and created a new one with Id 83 (Linux).
After some parameter changes with tune2fs i tried my test again, and the result was like it should be:
dd if=/dev/zero of=/media/disk/512mb bs=4k count=131072
131072+0 records in
131072+0 records out
536870912 bytes (537 MB) copied, 21.8862 s, 24.5 MB/s
For me this looks like a BUG in the QNAP software, so please check !
