Not too long ago, even the biggest and most expensive memory cards could only handle a few gigabytes of data. Things have come a long way since then, and these days you can fit an entire terabyte of storage into a chip that’s smaller than the tip of your finger. And you can pick up packs of smaller-capacity cards for a dime a dozen.
As you can probably infer from the name, microSD cards are an even smaller version of the standard SD cards used by most digital cameras. They’re primarily used in phones and tablets, where size is a major factor, and it never hurts to have a few extras on hand. And right now, you’ll find plenty of these tiny memory cards on sale with big discounts. We’ve rounded up some of the best deals on microSD cards out there below, and we’ll continue to update this page as offers come and go. Be sure to check back often to make sure you’re getting the best price available.
SanDisk’s Extreme series is built to withstand harsh conditions, so they’re ideal if you’re looking for a memory card for your GoPro or another action camera. This card is resistant to water, shock, extreme temperatures and even X-rays. Beyond its durability, this card boasts some impressive specs. It has read speeds of up to 160 megabytes per second, and write speeds of up to 90MBps for fast shooting, plus a respectable 512GB of storage. This is one of the best overall values you’ll find out there at the moment.
If you’re looking for serious storage capacity, this is the one of the best deals you’ll find out there at the moment. This Lexar has an entire terabyte, or 1,000GB, of memory.

Whether you have the original Switch, the Lite version or the new OLED, you’re going to want some extra storage for your console.

It’s also fairly durable with protection against extremes, water, shock, and x-rays, and boasts read speeds of up to 100MBps.
This Samsung microSD only has half the storage capacity of the 512GB SanDisk Extreme listed above, but it also costs less than half the price, and is more durable. This 256GB chip is protected against water, shock, drops and temperatures, as well as magnets and X-rays. It’s designed to capture 4K UHD video and boasts transfer speeds of up to 130MBps.
