Over at this year’s Mobile World Congress, SanDisk introduced what it claims is the world’s highest capacity micro memory card. This 128 GB SanDisk Ultra microSDXC USH-I promises to meet the growing storage needs of mobile device users today.

Even with the prevalence of affordable cloud storage, removable and portable physical storage still has a place today, particularly in this increasingly mobile world. Aside from providing instant access to files even without an Internet connection, memory cards provide an expanded storage space for recording and storing videos and photos from smartphones with ever improving camera features.

SanDisk pushes the limits of microSDXC cards in both capacity and speed. The company employed a new proprietary technique that vertically stacks 16 memory die into one chip, allowing the super high capacity card to reach that new 128 GB limit. But the card doesn’t only boast of a large storage but also of high I/O speeds, making the card ideal for recording videos even at 1080p Full HD quality.

This new high speed, high capacity memory card is now available with a suggested price tag of $199.99 from retailers, though it will be exclusive to Best Buy and Amazon in the US. SanDisk will also be providing an updated Memory Zone Android app for accessing and backing up their files. This updated version will feature a new OptiMem option that will monitor the device’s internal memory and automatically backup old photos and videos to the external storage.
