    Hey folks,

    I'm looking to buy a 8gb or 16gb microsd card. I prefer stability over crazy amounts of memory.

    I saw this site's store links to this SanDisk 16GB card @ $40.

    But when I go to newegg, where it is only $25, it says that it is a Class 2 card. Is that correct? Is that fast enough?

    Thanks.

    I have a Samsung Focus 1.3.

    I'm looking for an 8GB or 16GB because I don't want to spend a whole lot. I'm looking to spend $20 at most.

    16GB Class 4 for $15

    16GB Class 4 for $14.50

    16GB Class 4 for $15.24

    16GB Class 4 with adapter for $18

    16GB Class 10 with adapter for $19 or $21

    16GB Class 10 with adapter and USB reader for $20

    A friend of mine told me that she read that class 10s don't work properly with her Android phone, so if you are thinking about class 10, do read up first, just in case.

    Thanks for the list. Are these guaranteed/certified by anyone to work with the Focus? I hear so many horror stories of weird problems with performance after installing SD cards.

    I travel a lot so my Focus really needs to be reliable more than anything else.

    Thanks!

    I'd stay away from higher class cards.

    Class rating refers to how fast you could read and write sequential data on a card. Like for taking a lot of quick photographs. Or for video.

    WP will be accessing data randomly, not sequentially. So the class rating means nothing to WP. Well, except that a card that has been optimized for sequential data read/write might not be very good for random read/write. So a higher class rating could be detrimental.

    The only card I've heard of being officially supported (according to the Focus user manual) is the 8 GB SanDisk Class 2 card.

    Right now, there is no consumer rating system that rates cards on the speed of random read/write. So there are no commercial products available where you could definitely know it will work.

    OEMs have their own ways of measuring this for the SD cards that they may use internally. But those obviously haven't made their way to the consumer.
