Having the same trouble after updating one of my RB951G-2HnD to 6.28: around 2 sector writes per second. Reboot seems to help to make it stop.
After messing around, I discovered that once WinBox is closed, the counters are not growing anymore. In other words, you can disconnect WinBox, log in a few minutes later, and discover the same sector write count. It starts to grow again at the same pace when I open IP -> Firewall -> Filter/Mangle view in WinBox. Closing IP -> Firewall view still keeps the counters growing. Closing the WinBox session, and connecting again (IP -> Firewall view closed!) stops counters from growing. I would guess some background thingie that reads firewall stats is writing on disk.
