While possible, the maximum theoretical throughput of USB 2.0 is 480Mb/s (megabits per second), or 60MB/s (megabytes per second). In real life, you probably won't get more than half that (and even then, only with a really high end thumb drive). Unless your hard drive transfers data slower than 30MB/s, it is better to just have a swap (virtual ram space) partition on your hard drive. This is over simplifying it a bit, since hard drives have longer latencies than flash drives, but the gains are still probably more trouble than it's worth, especially considering how fast that would destroy the flash drive with writes.Originally Posted by rob_1980
Using the graphics ram, on the other hand, will yield significant performance increases, at least when you don't need it for graphics stuff, of course.
