Toshiba may have claimed a world’s fastest title with its new Exceria Pro SD memory cards that come in 16 and 32 GB capacities, but SanDisk is claiming its own world's fastest crown – this time for a 64 GB microSDXC card.

While not as fast as the blistering data write speeds of up to 240 MB/s that Toshiba is claiming for its SD cards, the up to 80 MB/s read and 50 MB/s write speeds SanDisk is quoting for its Extreme microSDXC card are nothing to sneeze at. The card is aimed those looking to expand on the inbuilt memory of newer tablets and mobile phones and shutterbugs not averse to continuous burst mode and quick file transfers.

SanDisk says the card’s UHS-1 and Speed Class 10 video recording ratings ensure it is capable of recording and playback of Full HD and 4K HD video. The card is also waterproof, shockproof, resistant to x-rays and capable of operating in temperatures ranging from -13 to 185° F (-25 to 85° C). It also comes with an adapter to extend compatibility to devices sporting SD and SDHC slots.

The SanDisk 64 GB Extreme microSDHX card is available now for US$199.99.

Wonder what will be its price in India where a Sandisk 32GB class 10 micro card is available for around Rs. 2,000.00 ($ 33.00) . I bought this 32GB class 10 micro card for my Samsung Galaxy Grand for Rs. 1,800.00 in Feb. 2013! The indicated price of $ 199.99 will translate to Rs. 12,000.00 appx. !

May want to proofread that third paragraph. I'm pretty sure the company's name is SanDisk.

If you're wanting to use it in a GoPro - google it before you buy it - rather a lot of these are self-destructing in those cameras for no apparent reason.


Cool. I have a regular 64GB microsd card in my amdroid and it works fine. Bought it last year for 60 bucks
