Hello,
After 3 years of working with my NAS I recently had disk failure (bad block found). I replaced it with same model (WD Red 2GB - just a single drive, no RAID or anything) but now I'm experiencing significantly slower speeds after the disk is on for some time. I have to restart the NAS to get the speed back. It is especially pronounced when I'm working with a lot of smaller files.
I've never experienced this with my old disk - does somebody know what could be the problem?
Thanks in advance
Vuk

Re: Disk speed slowing to a crawl
Hi,
For the forum, please provide more information
... A.D.M. version, the model and the memory if you change / increase it
... did you change the file system (ex. from ext4 (default 3 years ago) to btrfs now default)
... how did you do the copy of the data or did you used a clone tools or restart from fresh install
... post interesting information, like result of command like "df -h" "top" screen capture ... any information about the disk & system activity

Re: Disk speed slowing to a crawl
Hi Phillipe, thanks for answering
I'm running ADM 3.4.5RBJ3, still default 512MB memory
I did not change file system, I used wizard for creating a partition like 3 years ago, I don't remember it gave me a choice of which format to use (now I checked it's ext4)
I copied files from defective disk by connecting external disk to NAS and manually copying. And vice versa on the new disk.
Hopefully I'm attaching image with result of df -h and top
Thanks again for your help, it's getting to be impossible to work with it.

I think you should try to install this package: viewtopic.php?f=240&t=10717

Didn't help unfortunately. Something else must be amiss

Re: Disk speed slowing to a crawl
Oops, I thought it's caused by "watch_storage". You'd better to send a support ticket to asustor directly. https://support.asustor.com/
