USB boot drive utilisation over 65% on average constantly

Hello gentlemen,

The last few days I am seeing that my usb boot drive utilisation is constantly over 65% on average. Is this a sign that the drive is slowly failing and I have to consider its replacement? My Netdata iowait monitors suggests so, since the drive is now a bottleneck for my system.

As an example, I am having constant dropouts when even when I am streaming a 40MB Flac file from my nap to my local streaming device.

This behaviour was absent a week ago...

Any thoughts on the above?

I don't know what happen but the CPU load has dropped to only 1~2% from last night.

Maybe it was doing some short of indexing after the last update to 5.6.4-1....
