SanDisk has introduced the first 200GB microSDXC card a while ago and it's currently on the markets. Now, a company called Microdia, and while it doesn't quite have the same brand recognition as the memory card giant, this California-based company also makes flash memory and accessories. Microdia introduced the first microSD card that stuffs 512GB worth of storage space into a piece of plastic smaller than your fingernail.
Naturally, it won't be cheap. Microdia says it estimates the Xtra Elite will cost around $1,000 which converts to around £655 or AU$1,285 when it goes on sale by the end of this year, though that's not the final retail price. You can buy a 64GB card for around $30, £18 or AU$35.
The Xtra Elite will use version 4.0 of the Secure Digital standard, and feature an Ultra High Speed (UHS) bus with data transfer rates of up to 300MBps. Because it's using SD 4.0, the card features an additional row of pins below the standard ones.
