There is little to no quality control on this card. I bought 4 originally, 3 of which had various problems (of which one didn't even register). The memory transfer rates are sporadic and unreliable. I have copied files to it and it said everything was good but the destination was corrupted. I isolated this by moving it to a completely different computer with the exact same results. The flash drives were of similar issues and thus I have given up on Adata memory. Your experience may vary.

It maintains the proper data strength as prescribed.

It will fail with out warning. Make a backup if you have valuable files on it. I have bought 5 of these products and they all have failed. I had only one fail within the warranty period. The rest just outside of warranty. I just went to memory express to replace 3, I bouht another brand.

If you need it for quick transfers or data movement it works very well. Overall it's cheap and you et what you pay for period. Don't be cheap with your important data, like me!
