During Mobile World Congress in Barcelona, SanDisk announced their largest-capacity MicroSD card ever with 128 GB of space. Thanks to WPCentral forum member, NoRomBasic, we can see that the SanDisk Ultra 128 GB microSDXC card works with the Nokia Lumia 1520 . Initial tests suggest that the card has no performance issues to worry about.

The card is supposed to retail for $200, but Amazon currently has it listed for $119.99. The bad news is that it's currently backordered by a few weeks. This is great news for people with expandable storage capabilities on their phones and tablets.

NoRomBasic has included these reports on the forums so far:

It benches about 20% faster than the SanDisk Ultra microSDXC 64GB.

I did record about 5 minutes of video last night and had no stuttering issues, as well as played back an episode of Firefly formatted in 720p low-compression WMV format. Card seems to work just fine.

Head over to the forums to follow up on these cards. Are you planning to get one?
