All microSD / microSDHC memory cards are not created equal; for example, many 32GB microSDHC flash memory cards are rated Class 2, meaning they have relatively slow data transfer speeds to and from the card.  But if you want faster read/write performance, you do have options.

For example, PNY has a Class 10 32GB microSDHC memory card with 20MBps (megabytes per second) read speed and 10MBps write.  This card will work well in newer Android-powered smartphones and tablets, as well as digital cameras (with an SD adapter) and other devices with memory card slots.  You can check your product literature to see how fast a card your device supports. 

But you’ll pay a premium for faster performance; a 32GB Class 2 SanDisk microSDHC card can be purchased for just over $40, while the Class 10 PNY will set you back $68. 

If you spend a lot of money on a high-end device, it may be worth your while to avoid data transfer bottlenecks with a faster memory card.
