Hi folks, I recently picked up the BuyDig J4/WP-N3 sale package for scuba diving, and was curious if anyone tried a high-speed card like the SanDisk 32GB Extreme PRO UHS-I card in it, and it if had any real-world benefit. The package came with a 32GB Sony SR-32UY microSDHC card, and it seems to me to be pretty slow to write to. I can't find any specs for this card, so I don't know what it's rated write speed is. The Sandisk above has the fastest write speed of 90MB/s, but can the J4 really take advantage of this capability? There's no point in buying it if it doesn't.
So if anyone's tried a high speed card in the J4 and had real-world throughput increase, please let me know. Thanks.
If this is your card, it's only guaranteed to 10MB/sec write perf, a U3 would be faster, note the star next to the 40MB/sec and the 1 inside the U.
If you're not a diver and go to depth beyond 1 atmosphere (33ft), chances are whatever underwater case you use will hold up. It's in the greater pressures where leakage can occur. Because the WP-N3 is custom made by Nikon for this series of cameras, I have a bit a faith in it's functionality. :-)
