SanDisk Intros World's Fastest 64GB MicroSDXC Card

On Tuesday SanDisk revealed the SanDisk Extreme microSDHC and microSDXC UHS-I memory cards, several storage solutions for customers who want fast expanded memory in their smartphones, tablets and cameras. They're available worldwide now in 16 GB, 32 GB and 64 GB capacities costing between $59.99 and $199.99 USD.

According to SanDisk, the 32 GB and 64 GB models provide read speeds up to 80 MB/s and write speeds up to 50 MB/s. The 16 GB model provides read speeds up to 80 MB/s and write speeds up to 30 MB/s. The 16 GB and 32 GB cards feature microSDHC (high capacity) form factors whereas the 64 GB model is a microSDXC (extended capacity) card.

The company said all three cards have UHS Speed Class 1 (U1) and Speed Class 10 video recording ratings, promising higher performance than ordinary memory cards to deliver Full HD5 and even 4K HD video recording and playback without interruptions. They're compatible with the latest cameras and Full HD camcorders, allowing users to quickly capture videos and pictures.

"Most high-end smartphones are now driven by high-speed quad-core processors, which deliver Full HD content and applications to large, high-resolution external displays," said Stuart Robinson, director, handset component technologies service, Strategy Analytics. "Such applications require high memory bandwidth which is ideal for the SanDisk Extreme microSDXC card, the world's fastest microSDXC memory solution."

The company said that all three microSD cards are waterproof, shockproof, resist x-rays, and are built and tested in harsh conditions. They also include an adapter for compatibility with full-size SD / SDHC / SDXC supporting devices, a downloadable offer for RescuePro Deluxe data recovery software, and a lifetime limited warranty.

    Most phones have USB 2.0 so you have to put into an external USB adapter to take advantage of the higher speeds speeds.
