I have an aging dell Dimension 1100 desktop. I'd like to use flash memory for virtual memory. I have usb2 ports but can I get faster data transfer rates and how much faster by connecting elsewhere? Can I get fast enough to use a usb3 flash memory? One possibility is to put in an adapter and connect via the PCI slot - bus speed 33MHz - would this be significantly faster than using the usb2 port? Would I notice differences from using the HDD for virtual memory? I have a spare HDD slot is there an adapter so that I could connect my flash stick there and how much faster would that be? Any other ideas?
