Our take on the Samsung PRO Plus 512GB MicroSD Memory Card + Adapter
The Samsung PRO Plus is a high-end microSD card aimed at action cameras, drones, phones and handheld consoles. It uses Samsung's own NAND and controller, and the line is rated for U3, V30 and A2 speeds, so it handles 4K video capture and app installs on phones. The 512GB version gives you room for long recordings and large game libraries, and the included SD adapter lets you slot it into a laptop card reader. Against SanDisk Extreme and Lexar cards it trades blows on speed, with Samsung's reputation for reliability being its main selling point.
