The back of the packaging provides a bit more information regarding the features and capabilities of Samsung's P9 microSD Express card. Along with its speed classes and grades, the packaging shows that it is covered by a 3 year warranty and is water, temperature, x-ray, magnet, drop and wearout-proof.
Physical Features:
As you'd expect, Samsung's P9 microSD Express card is quite small. It measures 15 x 11 x 1.1 mm and weighs in at a mere 0.25g. The card is constructed out of white plastic with black and red printing on top of it. Along with the Samsung logo, the card shows the capacity, model and speed class ratings.
On the back of the card, you can see two rows of pins as well as the model number, production batch and serial numbers and the country of origin. In this case, the P9 is made in Taiwan.
The big difference between microSD Express cards like the P9 and your average, run of the mill microSD card is the second row of pins. This second row offers support for PCIe technology for greater speeds and lower latency. Looking at the screenshot below, you can see that the P9 is recognized as an NVMe storage device with features like S.M.A.R.T. and TRIM.
