SanDisk Extreme microSDXC UHS-I Memory Card Review

Article Index:   

A couple of weeks back, SanDisk launched a new line of Class 10 UHS-I microSDHC / microSDXC cards targeted at performance conscious consumers. When describing the cards, SanDisk’s director of retail product marketing Susan Park said, “The SanDisk Extreme microSDXC card allows users to do more with their devices…Our high-performance and high-capacity microSD cards enable consumers to take advantage of the high-quality HD video and imaging capabilities in the latest 4G smartphones, tablets and action cameras."

With up to 80MB/s read and 50MB/s write speeds, the new SanDisk Extreme microSDXC cards should easily be able to handle the needs of users taking photos and videos on today’s mobile devices, be it a smartphone or tablet or even a high-end camera. And with capacities up to 64GB, the cards offer plenty of storage space too.

We’ve had the top of the line 64GB SanDisk Extreme microSDXC card in house for a couple of weeks now and it’s worked flawlessly in a number of devices, ranging from a new Olympus PEN camera to an as-yet-released portable gaming device. Compatibility is one thing, but we figured many of you would be interested to see if SanDisk’s performance claims were realistic too, so we ran a couple of benchmarks on the thing to see just what it could do. Before we get to the numbers though, here are some pictures and specifications...

Save for its red and gold color scheme, the SanDisk Extreme card looks just like any other microSDXC device (obviously). Included with the cards is a simple adapter and a plastic case (not pictured). Other than that, there’s not much else to report in terms of the product’s aesthetics or bundle, though SanDisk does also offer a downloadable copy of RescuePro Deluxe data recovery software should you register the product and the company claims the cards are waterproof, X-ray proof, temperature proof, and shock proof as well.
