Mini SD Cards

Technological innovation constantly leads to new developments in consumer electronics--many of which conveniently make products smaller, lighter, and cheaper. Portable memory has undergone some major advancements over the last couple decades, allowing users of portable electronics to store more files on their devices. SD cards have been embraced by most major manufacturers as a convenient means of file storage, and mini SD cards are even smaller than the standard variety. Here at Walgreens, you can find mini SD cards from brands like Duracell and SanDisk that can interface seamlessly with your electronics.

What is SD Memory?

Easily one of the most popular portable memory mediums, SD is short for Secure Digital. These memory cards can be used in devices like mobile phones, cameras, tablet computers, and GPS systems. A form of solid-state storage, one major advantage to SD memory is the fact that the cards don't contain any moving parts--which makes them much less likely to malfunction. The cards also tend to have very generous storage capacities for their size, and they might range from 1GB up to 64GB. Different cards vary in terms of how quickly data can be written and read, and you can find products in a variety of different speed classes. In addition to being the standard choice for most portable electronics, you'll also find SD ports in many modern computers, which make it easy to transfer data to and from the card.

Uses for Standard, Mini, and Micro SD Cards

In addition to variations in storage capacities, you'll also find that SD cards come in three distinct sizes. Standard SD cards measure 24mm by 32mm and are the most common variety used in slightly larger devices like digital cameras. For mobile phones and other petite devices, mini SD cards (21.5mm by 20 mm) and micro SD cards (15mm by 11mm) were introduced a few years after the standard cards. You can check your owner's manual to find out exactly what type of SD card fits your particular device. Since most computers can only read standard cards, many mini and micro SD cards are sold with adapters that will allow you to insert them into larger slots.
