Hi,
Can you suggest any reliable USB HDD transfer speed bencmark application?

I intend to use it with external USB HDD, as Plextool measures limited USB DVD reading speed on one PC, if to comapre the same USB DVD reader on another PC.
The questiopn is actually, how to measure USB spead without loopback, but I guess it isn't possible, so I can use another USB HDD box as comparative measuring tool.
