SanDisk's Ultra SDXC and microSDXC memory cards make their way through the lab. Follow on as Tyler puts them through their paces to see how they perform.

The card that I received is a corrupted one and not even able to format it.

Okay, we've been using Sandisk products for many years. Our oldest card was 32kB (not MB or GB) and cost $69. We've had great results with their products (except some fake ones) over the years and this one is no exception. It's very fast (over 100MB/s in testing) and has been very reliable in use.

It appears to do what it is supposed to. Its an SD Card,slotted easily into my new phone no problem. The real test will be if I fill up my phone memory and then fails.

This card is perfect for the Mavic Pro 2 which is the reason I purchased. Slower cards cant handle the 4K footage or Raw files to be able to covert to hyperlapses. This card can handle it all and at the time I purchased it, it was on sale for $60 which is a deal because I tried finding it locally...

Well packed .. working as expected. Nice shopping experience.

It gives approx 59.70 gb on my Asus Zenfone Selfie. It really is quite nice. Just bought the product a week earlier and it does its job as its supposed to :)

Really good microSD card, use it in my Xperia Z1, goes really fast to transfer and no problem to play games or watch movies stored on it. A slightly pricey perhaps, but be it as it is faster than the others.

In June 2012, SanDisk announced the world's fastest microSDHC mobile memory card with the introduction of the SanDisk Extreme Pro microSDHC UHS-I card series. The cards were available in just 8GB and 16GB capacities, but made up for the rather small sizes by being incredibly fast.

Need more space on your Android phone or tablet? Of course you do. Even with the number of apps and services moving users to the cloud, nothing beats having a bunch of local storage for pictures, videos, games, and apps.
