Not all SD cards create equal!!!

It was an awesome day here in MD to fly and I burned through all three of my Mavic batteries and three on my P4P which meant I filled up two of my 64 Gig which I got on Amazon when I first got my P4P in February.

Amazon.com: SanDisk Extreme PLUS 64GB microSDXC UHS-I/U3 Card with Adapter (SDSQXSG-064G-GN6MA): Computers & Accessories

Well the other day I saw these on Amazon

Amazon.com: SanDisk Ultra 64GB microSDXC UHS-I Card with Adapter, Grey/Red, Standard Packaging (SDSQUNC-064G-GN6MA): SANDISK: Computers & Accessories

And for the price I ordered two... I put the first one in the P4P and after the first two minutes kept seeing in the SD Icon "slow writing" or something to that effect. Over and over again the same message. So buyer beware!! Spend the extra and get the good cards.

That is all....

The Ultra only writes at a max speed of 15MB/s. That won't be fast enough unless it can sustain that max write speed the entire time.

I have a list of memory cards that are known to work well with the P4P here. You shouldn't have a problem if you use memory cards from that list (or other memory cards with similar specs).

Sure now ya tell me!

Needless to say they are going back to Amazon on Monday and two more of the Extreme are one the way due on Monday too!

Thanks for that list of memory cards. Is there any benefit of a 90 MB/s over a 40 MB/s card?

40 MB/s should be sufficient for most people. With a faster memory card, you'll be able to transfer data to/from the memory card faster. It might make sense if you're transferring data from multiple memory cards daily.
