file system damage on flashUSB

I'm on Debian, I formatted a flashUSB3 with BTRFS and put on it a VM., that I had previously on an HDD.

At the beginning everything work as expected, few boots was very fast, and guest responsive, I can work well with the guest.

After some days, the guest OS start to freeze, report error, and also Debian kmesg show BTRFS fs csum errors. I tested the flashUSB with badblocks, no error. I checked the flashUSB with $ f3probe --destructive, and the flash is the real thing.

So I tried to format the flashUSB with ext3, exported the appliance again from HDD to flashUSB but after some days happened the same.

I changed the flashUSB (was a Philips) with a brand new Kingston, same happen.

I changed the flashUSB with an USB3 HDD, and everything work. I changed the HDD with an USB3 SDD, and everything work.

Now I'm sure there is bug with flashUSB3 ?
