Enabling 'Solid-state Drive' checkbox hangs Win10 guest

[ngoonee1]

Title basically says it all. I've a Win10 guest which I've used extensively, and it stopped working a whiles ago. Being busy I assumed it had gotten corrupted, and only recently did I have time to restore a backup (80 GB transferred remotely isn't quick).

The backup had the exact same behaviour, that is to say it would start up and do continuous I/O on the hard disc (I had it on an SSD). Same behaviour after moving the disk image to a HDD. The VM itself would not completely boot, most times. Sometimes it would get to desktop, but I would never get to actually do/run anything.

After lots of trial and error turning off the SSD checkbox fixed it, the VM works as before.

My host is Arch Linux 64-bit, and both my SSD and HDD are using the BTRFS file system. Virtualbox version is 5.0.20.

Do you have excluded the virtual disk image from BTRFS cow?

Also, please attach a VBox.log from a faild and a successful run.
