SanDisk 8GB Class 2 MicroSD Is First WP7 Certified Card

Sorting out a MicroSD card for your WP7 device is tricky. Very tricky. We’ve heard all sorts of different claims about what cards are and aren’t okay, but the eventual truth is that they need to be certified usable by Microsoft and the OEMs. Well, we may just have heard word of the very first officially approved card. On Samsung’s support page for the Focus it says the following:

Compatible micro SD cards will be branded as “Windows Phone 7 Compatible” on the packaging. Approved cards can be obtained from the manufacturer or carrier. (The SanDisk 8GB class 2 micro SD card has been certified.)

That’s right folks, the SanDisk 8GB class 2 should work on your phone. If that’s true, why didn’t the identically classed 32GB card work?

It’s all very confusing right now.

Samsung does go on to warn that inserting a MicroSD may make it non-functional on other devices:

Once inserted and properly formatted, the memory card becomes an inseparable part of the phone. A micro SD card inserted into a Windows Phone 7 device, and integrated into the device’s file system, is intended to be a permanent modification to the device. Once a micro SD card has been integrated into a Windows Phone 7 device’s file system, it will no longer be readable or writable on any other devices such as computers, cameras, printers, and so on. This includes an inability to format the micro SD card for use in these devices.

    I’m guessing that they are working with a slightly updated version of the OS. I’m not putting a single other card in my phone until I’m getting double thumbs up from the manufacturer, carrier, AND Microsoft. I suggest everyone else do the same. When these phones are fully functional (i.e. without a card) they are smooth as silk with everything you throw at them. I’m completely in love with my phone without the card. I’ll be slapping one in soon as I’m confident which will just make it even more awesome. Cheers.

    and let me guess, they will cost 50% more than the same card did a week ago.

    I scored a Kingston class 4 32Gb for $40 and it works great. This is just an attempt to rip people off.

    well the card may work now but if you havent crossed the the 8gig threshold yet it may crash thereafter. could be an hour from then or a week after. I used my SansDisk 16gig class 4 and after it week the phone randomly restarted and everything was wiped from the phone. I am holding off until I get the nod from samsung or MS. done. Good luck with yours, you might luck out but to all others, lay off the Sans 16g class 4.
