Use the SanDisk Extreme.
More than exceeds any camera specs...
It's a V30, U3, A2 rated card.
Nice thing is it's available for a great price compared to Plus & Pro and basically no loss in performance.
The Extreme, Extreme Plus, and Extreme Pro have exactly the same substained "Write Speed" of 30MB/s referred to as Min Write Speed... this is actually the "Video Speed" Write.
The Listed Max Speed: Extreme 40mb/s, Extreme Plus 60 mb/s, Pro 90 mb/s is "Photo Speed" Write.
Which is a little misleading since every still photo camera can easily use 40 mb/s and if several burst it's cache will handle several frames.
For Drone usage capturing still shots for terrain maps, the V30 / A2 rating is the fastest recognized for aerial speed settings fo mapping stills and all 3 cards: Extreme, Extreme Plus & Extreme Pro share this rating.
Memory Card Battle: Sandisk Extreme Pro vs Extreme Plus vs Extreme vs Ultra
The main difference is price.
The Extreme can be found at great discounted prices.
Amazon has the 64MB Extreme listed at a super price of $14.40 each, the 128mb @ $24 with a max of 4 per order. The 64MB easily meets 1-3 flight missions, and I prefer to swap cards between missions. I personally purchased 3 sets (12 cards)... 3 orders of 4 each @ $63 total each set.
For external backup & capture: I use the Lacie CoPilot BOSS 2TB unit... throw in the card, 1 click and copy the card unattended. Later via iPad, Android or Computer access the files directly on the CoPilot.
For additional security, 2 CoPilots can be in a "Clone mode" where salve unit maintains a clone of master with a click to sync.
NOTE: if you grab a CoPilot... out of the box FW does not support iPad Pro USB-C. Requires a FW update using a iPad Lighting plug or Android. After update, works great with USB-C or even the Hyper Block.
