SanDisk 200GB Ultra Card
Next, we'll recommend what's perhaps the best overall price/performance card on the market. The SanDisk 200GB Ultra MicroSD. It's not as affordable as a 64GB card, but it's still pretty cheap yet you get a ton of space.
I consider it the best bang for your buck and use one myself. The SanDisk 200GB Ultra is perfect for video recording thanks to 90 MB/s speeds. Not to mention will fill all your music, HD movies, slow-motion clips or games. SanDisk is one of the most popular and trusted brands in the industry, so get this knowing it's a great choice.
If you buy this online you'll pay the same price as most local retail stores want for a 64GB card. Seriously.
