What is a memory card?

A memory card is flash-based storage that typically comes in a slim, lightweight form. You can insert a memory card into a built-in slot on a device, via a memory card reader, microSD card reader, or with a similar adapter.

Memory cards save data on a wide range of portable devices, such as smartphones, cameras, and handheld gaming consoles — some even work with Chromebooks. Their simplicity makes them a prime choice for storage while on the move.  

Memory Card vs SD card vs microSD card

“Memory card” covers different types of flexible, portable data storage. One of the most popular card types, SD — or secure digital — memory cards feature a high rate of data transfer and low battery consumption. 

microSD memory cards are simply smaller versions of SD memory cards, built specifically for compact devices like phones or Nintendo™ Switch™, which have limited built-in storage capacity. 

How much can a memory card store?

SD memory cards and microSD memory cards come in multiple storage capacities to meet virtually every need, from saving family photos on your smartphone to shooting high-quality video with a GoPro™.  

While 64GB¹ and 128GB memory cards are popular choices for everyday uses, flash storage capacity can reach 1TB in a single card for more intensive requirements, such as 4K and 8K UHD video recording.
