External storage decision
External storage decision
I've run out of room for my VirtualBox guest storage drives, but when I tried to move them to my external USB drives they run painfully slow. Is there a setting or tweak that can alleviate this? Or is there a better solution for an external drive setup? Thx!

Re: External storage decision
If you want to run VMs from an external drive at a similar performance level to the internal drive then, in my experience, the USB interface, drive and cables need to be at least USB 3.0; and best to use SSD, not spinning HDD or USB Flash Drives, which will be slow.

Re: External storage decision
The speed of the OS will be affected by the speed of the media it runs from. If you have a slow drive and the OS is loading a lot of uncached data then it's going to be slow. There's no getting around that.TripleA wrote:Is there a setting or tweak that can alleviate this?
More cache inside the VM might help, i.e. a larger RAM allocation - PROVIDED your host can afford it. If your host can't afford it then allocating more RAM will make things way worse.
