AS-606T slow

Postby Dogstar » Thu Nov 01, 2018 5:58 pm


I have an AS-606T with 6 HDD in RAID5 mode. I have a Gigabit network and Link Aggregation 802.3ad is enabled.

Read and write speed are 60 MB/s max. I think 90 - 100 MB/s should be possible. What's going wrong here?

I had a similar issue and found one of the hard drives was probably about to fail and had SMART errors. Have you check each indidual drive in the ADM Storage Manage>Volume and expand all the drives to check their status.

If that looks ok and no issues with your HDDs, remove all connections from your router or switch, so only the NAS and PC are connected. Transfer a file and see if the speed returns to 90 - 100MB/s.

There maybe another connected device on your netowrk causing issues.

Also try using different ports in your switch or route to rule out any issue from that.
