I just updated to TOS7 on my F4-424 and noticed an interesting behaviour of the Device Monitoring app.

In the Home tab "Overview" it shows that both my installed HDDs are currently writing at about 100MB/s. System disk (M.2 SSD) is almost idle. no noticeable read/write activity

Under the "Disk" tab the monitored activity does not show the write activity clearly displayed in the overview. Instead, it seems to focus on system disc only.

Is there a way to select which drive / storage pool the data is basaed on?

Hello,

Thank you very much for your feedback! To help us reproduce and identify the issue as quickly as possible, we are currently trying to replicate the behavior you encountered.

Could you please provide the TOS version you are currently using? Also, could you confirm whether your device is configured with one HDD as the data drive and one M.2 SSD as the system drive?

In addition, regarding the disk-based data display feature you mentioned, it is currently only possible to view the I/O statistics of an individual disk from the Overview page. The good news is that this feature has already been added to our development roadmap and will be introduced in a future release.

Thank you for your understanding and patience!
