SanDisk has officially unveiled what it claims is the world’s fastest microSDXC memory card, the SanDisk Extreme 64GB.


The SanDisk Extreme 64GB is the largest-capacity model in the company’s microSD range, and uses the ultra-high-capacity microSDXC standard.

The card is rated for write speeds of up to 50MB/sec and read speeds of up to 80MB/second.

Far surpassing the Speed Class 10 SD standard, which ensures read/write speeds of 10MB/second, the SanDisk Extreme 64GB also meets the UHS Speed Class 1, which is designed to ensure you can record 4K video happily.

The card is also waterproof and shockproof, although virtually any microSD card will survive being dunked in water.

The SanDisk Extreme 64GB takes over from the SanDisk Ultra 64GB as the top-capacity, high-speed small memory card on the company’s books. That card is rated for transfer speeds of up to 30MB/sec, making the Extreme model significantly quicker.

Although 64GB microSD memory cards have been available since 2011, this remains the storage limit.

At the Extreme 64GB card’s launch, SanDisk marketing manager Ruben Dennenwaldt said the company is working on the next level of storage – 128GB – and is currently “making very good progress.”

Prices for the SanDisk Extreme 64GB have not yet been posted on SanDisk’s UK website, but the range tops out at $200 in the US.

If speed is more important to you than storage, SanDisk also offers an Extreme Pro range, which offers write/read speeds of 90/95MB/sec.

However, Extreme Pro cards only come in 16GB and 8GB capacities in the microSD form.
