Troubleshooting question

It ended up being a bad disk (disk 3 of 9) that, although reported healthy, was about to crash soon and when removed (and then replaced) cleared up all bandwidth/buffering issues. So...the big questions are still bugging me: 1) why did my Synology NAS report it as healthy, and require deeper reporting: 2) why would a fault tolerant (one disk hot swappable) RAID setup be bothered by a bad disk, but not a crashed or removed disk?

Anyway, thanks Simon! I appreciate the help to spur me on to uncover the culprits.

Thanks for posting this. It might help other users who experience a similar problem.
