THE SUPERIOR 256/512GB & SUPERIOR PRO 128GB

All three samples arrived in blister packs from where you can take a quick look at the cards themselves.

As expected at the rear of all packs you will find a few words about the cards in 14 languages and company contact information.

Each microSDXC card comes with its own SD adapter (only the UHS-II one however stands out).

At the top of all three cards we find the capacity and speed classification while at the rear we see the data pins.

The additional rear row of pins (adding up to a total of 16 pins - 17 for SD card use) used in UHS-II cards is responsible for their impressive performance boost.

From this review and on for microSDXC UHS-II card benchmarks we'll be using the Kingston MobileLite Plus microSD Reader (if something significantly better gets released down the road, we'll update UHS-II card numbers and use that instead).
