A microSD card is a microSD card, right? Not quite. Some are better suited for certain tasks than others. If you want to record video, you will benefit from using a high-speed card.Right now SanDisk's 32GB UHS-1/U3 Extreme microSD card is available on Amazon for a mere . This was already an affordable card, and now the price is well into impulse buy territory.SanDisk describes this card as meeting the new UHS Speed Class 3 (U3 for short) standard. This means the card has a minimum serial data speed of 30 MB/s. That number is three times what you get with U1 cards.This is a UHS-I card, not UHS-II, so bus speeds reach 50MB/s. But you're still looking at UHS Video Speed Class 30 (V30) for handling 4K UHD video. When it comes time to playback contact, the card offers read speeds of up to 90MB/s.In short, this is a good card for managing video and taking big photos. Plus it will also store other large files just fine. And if you want to jump up to the next size, Amazon is selling the 64GB option for over twice as much.Source: Amazon
