has anyone tried a Class10 ADATA 64gb? My local computer store has one on sale for $29.99, it goes up to 45mb/s which is 1.5x faster than sandisk. Considering on buying it
Are you talking about Canada Computers?
From reports I have heard both here and in other DSLR forums, they are not the most reliable card, but they can get the job done.
If your only intended use is to use the card with your GateWay - where you are not storing sensitive data - then I don't see an issue using the card. Plus, they've apparently got a three year warranty on flash memory, so if it were to crap out on you, you could always send it in for repair (depending on if shipping cost or not, plus time until they send a new one, almost never worth it).
As many have realized by now, although SanDisk is more expensive, you pay for what you get. Not every microSD card is the same.
As for compatibility, one user here reported an issue with his class 10 card, but turns out they just needed to use SD Formatter and the card worked fine.
Check out RedFlagDeals every so often as you might find a killer deal on a card, or just about anything else (Apparently Staples or Target was clearing out 3DS XLs for $100).
Best of luck!
