The vast majority of currently available Smartphones on the market use microSD cards in order to provide a boost of convenient and removable storage space for Documents, Music, Pictures and so on. Even though with Windows Phone 7, things will change since the upcoming mobile OS from Microsoft – even if it will support microSD cards, they will not be user swappable and accessible – the rest of the players on the market, both OS and OEMs will still support microSD cards.
Currently, microSD cards have a maximum capacity of 32GB as this is a limitation imposed by version 2 of the SD Specifications: “High Capacity SD Memory Card: More than 2GB (This version of specification limits capacity up to and including 32GB)”.
Don’t worry, there’s a new standard coming soon, called (micro)SDXC – XC stands for Extra Capacity while HC is for High Capacity, which also has its limitations: 2TB. The upcoming (micro)SDXC cards will have a storage space between 32GB and 2TB. As far as speed is concerned, they will be labeled UHS (Ultra High Speed), “the fastest performance category available today, defines bus-interface speeds up to 104 Megabytes per second for greater device performance in SDXC and SDHC host products”.
Now, tell us, what would you store on a 2TB microSDXC card in your Device?
