High-capacity microSDXC cards have started to appear in the market, thanks to the advent of 3D NAND. In August 2017, the 400GB SanDisk Ultra microSDXC UHS-I card was introduced. At the 2018 Computex, we saw multiple vendors (ADATA, PNY, and Team Group) demonstrating 512GB microSDXC cards.

Digital cameras and camcorders employ memory cards (flash-based removable media) for storage of captured content. There are different varieties of memory cards catering to various performance levels. CompactFlash (CF) became popular in the late 90s, but, has now been overtaken by Secure Digital (SD) cards. Many computing systems (PCs as well as smartphones) also support SD / microSD cards for augmenting local storage capabilities. We recently started in-depth evaluation of the performance of various memory cards. This piece evaluates one of the highest capacity microSDXC card currently available in the market - the PNY Elite microSDXC UHS-I 512GB version.
