[Solved] Load virtual disk file from external disk (USB)

Post by Mariano0 »

hi,

I would like to know if anyone has tried to run a virtual machine with the virtual disk file (VDI, VHD, etc) stored on an external hard drive (USB) without problems.

Could I lose information if the system is not in use and the external disk (USB) goes into idle state?

Detail: I have USB 2.0 and I do not know the read / write rate.

The maximum throughput of USB 2.0 is going to make it impractical to run most guests with the .vdi file stored there. I would expect that the performance will be so slow that at least one birthday will pass just while you are waiting for the guest OS to boot.

Thanks, it seems I'll have to find another way.

What do you think about using the caddy adapter from compactera Slim to sata and installing a second disc? Will it have the same speed as the internal sata?

PD: It's a notebook.

Even USB3 is not a fast option. It takes about 5 minutes for my Win10 VM to boot. I don't even want to try USB2...

Ok, loading a virtual machine from USB is a bad idea. I will continue with the idea of using a Caddy Slim to save the VM.

Thank you for your answers.

Best regards.
