The largest Samsung Galaxy Note 4 microSD Card is the SanDisk Ultra 128 GB microSDXC. The 128 GB maximum Samsung Galaxy Note 4 storage is enough to store up to 24 hours of HD (1280×720) video.
The SanDisk Ultra 128 GB microSDXC is very reliable and durable. It is waterproof, temperature-proof, X-ray proof, and magnet-proof. SanDisk microSD cards have always been very reliable in Samsung mobile devices overall.
Although the largest Samsung Galaxy Note 4 microSD card is the SanDisk 128 GB microSDXC, it is not the top performing card. With all of the space that it holds it does not have near the read/write speed of the top performing 64 GB models. The SanDisk 128 GB microSD card has a read speed of 30 MB/sec which is good for playing back music and videos. But the slower write speed of less than 30 MB/sec is less than optimal for recording videos, music, and taking pictures.
So what is the recommendation? If top performance is what you desire for taking photos and audio/video recordings then I recommend the Samsung Electronics 64GB PRO Micro SDXC or the SanDisk Extreme Plus.
With 64GB of storage, 90MB/s read speed and up to 50MB/s write speed, the fastest Samsung Galaxy Note 4 compatible microSD card is the Samsung Electronics 64GB PRO Micro SDXC. This Samsung card is available in 16GB and 32GB with the same performance in read/write speed.
A close second in speed with 64GB of storage, 80MB/s read speed and up to 50MB/s write speed is the SanDisk Extreme Plus. The SanDisk card is not only one of the fastest compatible Samsung Galaxy Note 4 microSD cards, it has a long track record of reliability.
But if the largest Samsung Galaxy Note 4 microSD card storage is what you need then look no further than the SanDisk Ultra 128 GB microSDXC.
