When you buy a memory card, what are you looking for? Additional storage, higher transfer rates, and good prices.  This card is often on Amazon's lightning deals and this is the second one I purchased! I use it in my Nokia 808, which is my phone and camera.  Storing 41MP photos needs a speedy drive, and this one really works wonders!  The additional space is also great for storage! The second one I bought for my laptop, it just stays in there in lieu of an SSD because my laptop only has an 80gb internal drive.  If it were possible, I would definitely install Windows to it, but this laptop will not boot from a memory card.Bottom Line:Need Space? Problem solved, 64gb is currently the max you can get.Need faster transfer rates? For a MICROsd card, it's about as fast as you can get (and if you can get faster, it'll cost a LOT more)Cost? Well, wait for a Lightning deal if it's too much, but the current price really is not bad.5 Stars.Additionally, the SD adapter works perfectly! Including the little lock switch to make it read only if you want.
