Greetings,
To share with you. There is some truth to that. Some of the older Samsung Galaxy (Tablet 3 10.1) are rated to handle UP TO 32GB cards. However, as far as this new Note 8, in my homework to make purchase decision, including according to two different reps at Samsung Customer Svc., the Note 8 does and can handle the 64GB card. Also a good Samaritan at BB showed me his Note 8 with the 64GB functioning flawlessly.
Now. A whole different 50 Cents is: Which card is better. That is how I found this site looking for info., to make decision on whether or not buy Sandisk Ultra Vs Extreme Vs Other Brands. I have seen a few reviews where Toshiba, Panasonic, Lexar, and even Kingston are mentioned with preference over Sandisk. In the language of those reviewers the bias line is so thick and evident that you can cover the Grand Canyon. A lot of emotion and boo hoo hoo blah blah blah. Thankfully, some other articles show better objective data that validate itself as well as some the contradictory opinions of readers to those bias articles. These latter include the Sandisk with significant acceptance and close parallel to those TOP PICK. In fact Sandisk is rated as BEST PICK. There is one thing also. Sandisk EXTREME Class 10 or EXTREME PRO are the cards with the better ratings. I found equally important that all those reviews/opinions I have read are in reference to cards speed/quality/reliability but in terms of professional digital camera photography. Once again, Sandisk is rated as the choice for the money when compare to Lexar and a couple others. And BTW, at discrepancy in reading speed of Toshiba 90MB/Sec Vs Sandisk 85MB/Sec. Please give me a break.
Getting back on track. As far as cards for the Note 8. Sandisk Ultra is the best choice according to some articles and even Sandisk website recommendation. So are PNY, Kingston, Samsung itself, equally good. So in the end, I think choices are abundant and it is all up to you individually what works in your particular situation.
Lastly, the reason I mention Sandisk, please I am not in their payroll. I have Costco membership and better price that anywhere else I have seen up to this moment. So I feel comfortable and empowered with info to make a purchase decision.
I found as well that some of these top cards excel in bench testing (So let's call them excel White Lab Rats) . That may not be the case in real life with the variants in processor from one machine to another. I have made a decision to buy considering all aspect I have read. In my situation my choice is a safe one with my plans of use and double safety by ultimately backing up to save in my external HD.
Murphy's Law. When is going down, hey, it is going down. Cards will fail here and there. It is not the end of the world.
