A few years back during CES 2009, I was introduced to the first microSD card that offered 16GB of storage space. Considering the card's size, which is smaller than the nail on your little finger, that was really a wow. But it's not a big deal anymore.
Kingmax, a big name among system memory vendors, introduced today the first microSD card that offers 64GB of storage space. To put this in context, the device would hold enough data to fill two and a half Blu-ray discs (some 24 hours of 720p content), in a space that's again smaller than your fingernail. The new card supports the microSDXC standard, where XC stands for "extended capacity."
Kingmax says the little module features a Class 6 rating, meaning it can read and write at up to 48Mbps. While this is fast for a microSD card, it would still take about three hours to fill it up or pull all the data off of it.
Note that it's unlikely your smartphone can handle the card, as most smartphones are designed to work with microSD cards in capacities of 16GB or lower. For this reason, Kingmax hasn't announced the pricing for the new card yet, but expect it to be available for purchase soon.
Also expect other vendors to soon introduce their own 64GB microSD cards.
