I want to buy a 64GB micro SD card form my Samsung Galaxy S4 (getting one next week ). I'm thinking about:
- Samsung Pro (read: 70MB/sec write: 20MB/s)
- SanDisk Ultra (read: 30MB/sec write: 30MB/s)
- SanDisk Mobile Extreme (read: 45MB/sec write: 30MB/s)
- ADATA (read: 30MB/sec write: 10MB/s)
All of them are class 10 and support UHS-1
The first three cost pretty much the same, ADATA is like 2/3 of their price.
The speeds provided are probably for sequential read/write. I don't know what it looks like in terms of random access. Does it even matter since this is only storage for data? (as far as I know Galaxy S4 doesn't allow you to install apps on SD card)
My second concern is recording videos in full hd. Will all of the cards handle it?
Finally will the phone take full advantage of the declared read/write speeds?
What is the most reasonable choice here?
