should this not of been asked before you bought the card?!?!
Its a good budget card, Been using mine about 3-4 weeks now and no real problems, the only downfall I found in this card when comparing it to the R4DS (what I used to use) is that you cannot delete files on the card natively (probably on purpose for newbies hitting random buttons and finding things don't work after that) , alternatively you can use Homebrew apps such as DSBrowser, DSOrganize, DSFile which all let you delete/copy/paste files. Otherwise its a good step-up from a R4DS and sounds like its faster than AK2, DSTT, SCDS1.
