I just complained on BYOB about the lack of affordable USB 3.0 drives and now the cheap USB 3.0 thumb drives are finally here. SuperTalent drives are $14 for 8GB and $29 for 16GB. Sweet pricing, but what kind of performance do you get with a $14 SuperTalent USB 3.0? Read on to see what performance you will get for a $14 drive.

The Math – USB Theoretical Speeds
USB 2.0 is 480 Mbps = 60 MB/s (which is just 480,000,000 divided by 8 to get 60,000,000 to get Megabytes)
With USB 2.0 speeds, around 60% of the theoretical maximum is to be expected, since over an additional 15% would be added just for overhead alone!
USB 3.0 is 5.0 GBps = 5,000 Mbps = 625 MB/s (same formula as above)
SuperTalent USB 3.0 Express Duo
I think the “Duo” stands for twice as fast as USB 2.0?

I bought one for me and one for Andrew although he may not like it as much after this post. ![]()

Super Talent 3.0 Express Duo Drive
The drive is lightweight but feels cheap. It looks like every other thumb drive I have seen. Of course it is only $14 so what do you expect?
The drives retail packaging seems stronger than the drive itself. They should have made the drive out of the same material.

I had already installed a USB 3.0 PCI-E host card from EVGA in my Core i7 PC. I used the drivers from the EVGA CD to install the card. I guess they stopped selling these?

Just insert the USB 3.0 drive like any other USB device.

Conclusion
The Write was almost two and a half times USB 2.0 speed while the Read was one and a half times the Corsair speed. These speeds seem to be in line with other inexpensive models by PQI and A-DATA but much less than the higher cost drives by SuperTalent, Kingston and A-DATA.
If you are looking to replace a USB 2.0 thumb drive, then the SuperTalent USB 3.0 Express Duo Drive is worth considering. That being said, if you want really high speeds then you should wait a while and see how the USB 3.0 drives look in 2011, or spend the money now for the higher priced USB 3.0 drives.
