Pushing the boundaries of portable storage, SanDisk has unveiled a new microSDXC memory card with an astonishing 200GB capacity. This is particularly impressive because SandDisk has continued to push more and more gigabytes onto a storage medium that is the size of the average human fingernail.

It's interesting to note that despite paying the cost of an average smartphone ($400) for the SanDisk 200GB Ultra microSDXC UHS-1 Premium Edition card, users may not actually be able to use it with anything just yet. Most devices that support microSD are rated to support up to 128GB cards for the time being, including the just unveiled HTC One M9. The new Samsung Galaxy S6 does not even support expandable storage, departing from Samsung's typical strategy of flagship phones supporting microSD cards. SanDisk rates the card speed at 90MB/s, which means that it will take in excess of 30 minutes to actually fill it up with data.

Also launched by SanDisk is a new 32GB dual-USB drive with a reversible Type-C USB 3.1 connector, and one USB 3.0 connector. Again, here isn't anything you can actually connect the Dual USB Drive to, with Type-C compatible phones and tablets expected to launch in the coming months. Whenever they do, this card will keep you ready though, and in the meantime, you can always use the regular USB plug to connect it to the vast majority of computers available in the market.

Neither of these products are actually launching just yet, with SanDisk just content to showcase the fact that it's ready with the next generation of products. Both will be available in the coming months, with the Type-C USB drive also expecting storage capacities higher than 32GB.

SanDisk has also revealed a new 128GB version of its popular iXpand Flash Drive range, designed to quickly transfer pictures and video from iOS devices to Mac computers or PCs. There are also updates to the iXpand Sync app, which now supports Apple's Touch ID fingerprint sensor on the new iPhones and iPads. The new 128GB capacity costs $150 (roughly Rs. 9,300) and is already retailing via Sandisk.com.
