Cheapest 1 TB microSD card
A 1 TB microSD card is a tiny removable flash storage card that slides into a microSD slot to add up to a terabyte of extra space. It's a popular way to store games, photos, videos, and apps on handhelds and laptops that support it. Before you buy, check the physical form factor (microSD vs. full-size SD), the interface your device accepts (microSDXC is the standard at this capacity), and whether your specific device officially supports 1 TB cards.

Before you buy
- Match the card's spec to what your device can actually use. A card is only as fast as the slot it sits in, so check your device's supported bus speed and speed classes rather than paying for the fastest rating on the box.
- Look for the speed class markings printed on the card. Labels like U3, V30, V60, and V90 tell you the minimum sustained write speed, which matters most if you record video or load large game files. Application Performance ratings (A1 or A2) indicate how well a card handles many small read and write tasks, which is useful for running apps and games directly from the card.
- Buy from a source you trust and verify the card after purchase. Counterfeit cards can report a larger capacity than they actually have, so check the card with a full-capacity test or by filling it with files and reading them back before relying on it for anything important.
Questions
Will a 1 TB microSD card fit my device?
A 1 TB microSD card uses the standard microSD form factor, so it physically fits any device with a microSD slot. Fit and compatibility go hand in hand, though: just because a card slides in doesn't mean the device supports that capacity. Check your device's specifications for its maximum supported card size and card format. Our device list on this page shows the models in our catalog that are known to work with 1 TB microSD cards.
How fast should my microSD card be?
Speed ratings on microSD cards include two things: the maximum read/write speed advertised by the manufacturer and the minimum sustained write speed guaranteed by the speed class (such as Class 10, U3, V30, V60, or V90). For general file storage and casual use, a lower class is usually fine. For recording high-resolution video or loading large game files, look for a higher V-rating. Keep in mind that your device's slot has its own speed limit, so a faster card won't help if the slot can't keep up.
Should I buy a new or used microSD card?
Flash storage has a limited number of write cycles, so a used card may already be partway through its lifespan and could be closer to failure than a new one. If you do buy used, test the card's full reported capacity and check for errors before putting important data on it. For anything critical, a new card from a reputable source is the safer choice.
How much microSD capacity do I actually need?
It depends on what you store. If you're adding a little extra room for photos, documents, and a handful of apps, 256 GB or 512 GB is often plenty. If you plan to keep a large game library, shoot a lot of video, or use the card as primary storage on a handheld or laptop, 1 TB gives you the most headroom and reduces how often you have to manage space. Think about your usage and how much you'd need to free up in a typical month.
