PNY Elite 128GB
Another potential choice is the 128GB PNY Elite card. This is a decent middle ground too, as it's very affordable.
In fact, 128GB is one of the most popular configurations, and everyone offers this size at competitive pricing. And while the SanDisk Ultra 128GB is pretty cheap, the PNY Elite delivers slightly better performance for just a few more dollars.
This is also one of the most durable SD cards you can buy. PNY Elite microSD cards use a "4-Proof technology". Being temperature, water, shock (drop) and magnet proof. They're built to last and come with a limited lifetime warranty. A perfect match for the water-resistant Galaxy S9.
Additionally, if you want SPEED consider this 128GB card from Delkin. It's $130 but delivers class-leading performance thanks to two sets of pins and lanes inside the card, instead of one.
