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 SanDisk Extreme microSDXC UHS-I memory card series are said to be the perfect companion for your smartphone, tablet and cameras. With read speeds of up to 80MB/s and write speeds of up to 50 MB/s the 64GB card also just happens to be the fastest 64GB microSDXC card available.

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.

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...

My son is thrilled!!! We bought 2 one for his phone and one for his computer. He needed these to free up memory since everything stopped working once I popped them in and transferred files to the card everything started running smoothly again. My son has his phone and computer back!

Tried the SamsunX EVO 32 GIG and it didn't last 3 months and my phone did not work well with it. This stick does well with my SamsunX Note 4. I am happy.

Plugged into my phone and bumped my storage up to 64 GIGS to add to my phones 32 GIG; It is nice to have some extra room

I bought this memory card to hold photos since I am a photographer. It is perfect! I can keep all the images I need on it and if down the line I need to add more, I can easily do that. It works great and I am glad I purchased it at Office Depot!

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.

Thought at first I had made a mistake, when my devices wouldn't read the card. So, I put it in my computer card reader to see if it would detect it. It could, so then I just reformatted it a different format. Then used in my tablet again and there was no problem accessing it.

I purchased three of these for Samsung S7 Samsung S2 Samsung Note2 They all worked fine, except I had some trouble with the Note-2 I had to put the disk in my windows PC first and format it as windows recommended. Then the note2 recognized the disk once reinserted into the phone.
