I picked up a USB 3.0 flash drive and decided to run a speed test. I gave it a go with a Patriot Supersonic Boost XT USB 3.0 Flash Drive (PEF16GSBUSB). This set me back twenty dollars.
With my little test I set the standard with USB 2.0. I moved a single 700mb AVI file at the rate between 4-6mb/sec. The other tests I did were with two and three AVI files. Doing multiple files is extremely slow at about 1mb/sec. Here is a detailed photo of the transfer rate of the one file:
I’ll admit I tried my USB 3.0 stick before the 2.0 and I was disappointed at first. I seemed to have forgotten how slow 2.0 is. Here I did a another speed test by moving a large zip file on one of my desktop USB 3.0 ports. The increase is 5x the speed capping at 25mb/sec.
I also tried my laptop, which is not a powerful machine by any means. However, I have two USB 3.0 ports and my results averaged about 24mb/sec in transfer speed, about the same 5x faster. When running in the USB 2.0 port I averaged about 20mb/sec.
Is it worth it to upgrade to USB 3.0? In the case of using a USB drive a lot absolutely! Since 3.0 are nearly the same price as 2.0 there is no reason to stay slow. I was still disappointed that I never reached that 10x speed.
The last tests I ran were with multiple AVI files at 700mb/each. Moving multiple files over is quite a bit faster. You can cut the time by 5x. So what would takes 25 minutes would take 5 minutes with many large files.
Once and a while I could get a big spike when doing multiple files – but not often enough. It happens totally at random.
I think if I forked over more money for a nicer 3.0 stick that has faster I/O it would stand out a bit more. It’s a nice little flash drive but it can never compare to the cheapest Solid State Drive on the market.
