Here are the results from CrystalDiskMark 3.0.1 (x64), connected over USB2.0 and USB3.0 respectively:

Very diligent with specs, and actually performing better at USB2 than advertised by ADATA.

Looks like a good deal for 30$. Some personal concerns:

• Neck strap is not included, so might need to buy your own off eBay or similar. Got 5 for 1$, shipping included.
• Aluminum casing is nice, but the plastic cap does not seem to hold firmly. I expect it to start falling off after certain time.
• Warranty is neither 1yr as specified on some retailer’s spec pages, nor lifetime as promised by ADATA on the packaging. The correct wording is product lifetime + 1yr, so you are getting at least 1yr warranty with it.

Overall, I would recommend this flash drive for offering good value for the price
