17392	The disk usage is nearly 100% when the .vdi file of a VM is stored on a Seagate SSHD	merced		"I added a Seagate SSHD (Solid State Hybrid Drive, a HDD with a 8GB flash to 
speedup reading of frequently used files) to my desktop computer a few days 
ago. After I moved the .vdi file of a Win10 VM to that drive and started the 
VM, I found the disk usage in Task Manager of the guest OS is nearly 100% 
and the system response is notably slower than VMs whose .vdi files are 
stored in an HDD. The disk usage of the SSHD in host OS is extremely high 
(80% to 95%) too, but I did not run any application at that moment. The same 
VM (.vdi file) runs very well when it locates both in a HDD and in a SSD.
When it runs quite slowly in the seagate SSHD, Task Manager shows that the 
VirtualBox process occupies most of disk operation times.
What is the matter?
