Samsung Intros 32GB Class 10 MicroSD Memory Card

They always say bigger is better, but is it really? When it comes to memory cards, that only works one way. We want capacities to go up, but card sizes to shrink -- not like you want a phone chunky enough to hold a CompactFlash card, right? Samsung just announced the production of its high-performance micro Secure Digital (microSD) cards with advanced data transfer speeds that support the performance requirements on fourth generation phones. That's mostly marketing speak, but here's what really matters.

The new 20-nanometer-class microSD cards have a class 10 speed rating suitable for seamless data storage and transmission of full HD video, meaning that they can write at 12 megabytes per second (MB/s) and read at 24MB/s, providing users with more than double the maximum write speeds of a class 4 rated 32GB microSD card. The new 32GB memory card incorporates 32Gb 3-bit NAND flash memory chips and a proprietary 3-bit NAND controller to deliver the high performance.


Mass production of its 20nm-class 64Gb 3-bit NAND designed on advanced toggle NAND architecture is anticipated for early next year, but there's no set price for this thing just yet. And that's a shame, but that's just the way it is.
