Whats the difference between microSD and Memory Stick Micro (M2) memory cards?
They look the same. The Shape and the Interface! The M2 or Memory Stick Micro is slightly bigger and uses a different interface standard than that of microSD. Phones typically support either one interface standard or the other. MicroSD is becoming the industry standard, except for Sony Ericsson. The M2 provides removable high-capacity storage for Sony Ericsson’s latest generation of mobile phones. What’s the difference between SD and SDHC? The “HC” stands for High Capacity. When the SD Card Association (SDA) rewrote the spec to allow for 4GB to 32GB cards, a change was needed in the actual card spec to allow for those larger capacities, hence the HC. Devices capable of reading SDHC cards can also read SD cards but a SDHC card can ONLY be used in a SDHC device. Why is faster transfer speed important? What are the different purposes or needs for different speeds? Most people are aware of a card’s capacity — i.e. how many files it can hold — but there is also a read/write speed per card
