The best microSD cards pack dependable and affordable digital storage into a very small package.
With tons of options available, shopping for a micro SD card can feel overwhelming. We chose our top micro SD card picks based on reliability, capacity, and speed.
Reliability: Like any digital storage device, micro SD cards can fail. We chose highly-rated micro SD cards from trusted brands to lower the chances of this happening. Plus, some of these brands also have warranties to back up their confidence in their products.
Capacity: Most micro SD cards available on the market today are micro SDXC cards, which have a storage capacity over 32 GB and up to 2 TB. We included micro SD cards that span this range, starting at 32 GB and going up to 1 TB, which is the largest option available today. Some older devices still require micro SDHC cards, so we included a couple of those on the list as well. The range of options on this list should cover most consumer storage needs.
Speed: A micro SD card that is too slow for the task at hand is a major nuisance. Nowadays, there’s not much use in cards with less than a Class 10 speed rating (a write speed of about 10 MB per second), and even faster options (like U3 and V30 options, which both equate to a write speed of about 30 MB per second) are usually better. We chose micro SD cards with fast read and write speeds to handle a wider range of devices and tasks.
Why It Made The Cut: With options ranging up to 1 TB (including 200 GB and 400 GB versions), this micro SD card is designed with high-capacity storage needs in mind.

For big storage needs, sometimes capacity is more important than speed, especially if you are looking for a cost-friendly option. The SanDisk Ultra micro SD line balances performance, storage capacity, and affordability, to offer micro SD cards as large as 1TB in capacity, without exorbitant prices.
While this micro SD card comes in a 1 TB size, it’s also offered in a range of capacity options — starting as low as 32 GB — to cater to different storage needs, including 200 GB and 400 GB options, to best balance storage and price. The wide range of options makes this micro SD card a great option for a gaming device (like a Nintendo Switch), phone, or tablet, especially for high-capacity storage purposes. Although it’s great for storage, this memory can also be used for other purposes. It has a Class 10 and U1 rating. With a maximum read speed of 120 MB per second and a minimum write speed of 10 MB per second, it can handle full HD videos, however, it is not ideal for recording 4K videos. The included SD adapter adds even more flexibility to its possible uses.
