To film with the Insta360 X6, I wouldn’t go looking for the cheapest microSD card. A 360° camera quickly generates large files, especially in 8K. A card that’s too slow can cause recording to stop, an error message, or painfully slow transfers. The minimum to aim for is simple: a UHS-I, U3, V30 microSD, bought from a reliable seller.
After checking the Amazon listings, I’m keeping three 256GB cards that suit the X6: the SanDisk Extreme for a no-fuss choice, the Samsung PRO Plus for a bundle with a USB reader, and the Lexar Professional 1066x as a solid alternative. All three carry the V30 rating, which is the single most important point for demanding video recording.
My quick pick
The SanDisk Extreme 256GB is the one I’d choose for most users. It ticks U3, V30, and A2, it’s designed for action cameras, and it’s very easy to find. Go for 256GB if you shoot regularly; move up to 512GB if you travel or plan to film long 8K sessions.
The three microSD cards I recommend for the Insta360 X6

SanDisk Extreme 256 Go
The simplest choice if you film with the X6 regularly.
- UHS-I, U3, V30 et A2
- Up to 190 MB/s read speed, according to Amazon
- SD adapter included

Samsung PRO Plus 256 Go
A good option if you want a USB reader included with the card.
- UHS-I, U3, V30 et A2
- Up to 180 MB/s read speed, according to Amazon
- USB reader included with this model

Lexar Professional 1066x 256 Go
A solid alternative for action cameras and longer shooting sessions.
- UHS-I, U3, V30 et A2
- Up to 160/120 MB/s, according to Amazon
- SD adapter included
Why a V30 card is essential with the X6
The V30 label indicates a minimum sustained video write speed of 30 MB/s. That’s the spec that matters most here. The very high numbers shown on the packaging often refer to read speed, i.e., transfers to your computer. They’re useful, but they don’t, by themselves, tell you whether the card will keep up during a long take.
The X6 records 360° video up to 8K. So it needs a stable card, not just one that looks fast on paper. The three models above are indeed U3 and V30, which is why I prioritize them over a card with no clear video rating. On the other hand, avoid no-name cards, A1-only models, or used cards whose origin can’t be verified.

128, 256, or 512GB: which capacity should you choose?
| Capacity | For whom? | My opinion |
|---|---|---|
| 128 GB | Short outings, occasional use | Possible, but you’ll need to empty the card often. |
| 256 GB | Cycling, travel, vlogging, regular use | The best balance to get started with the X6. |
| 512 GB | Holidays, road trips, lots of 8K | More comfortable if you don’t transfer your files every night. |
For an X6, I’d go straight for 256GB. The 360° format encourages you to shoot more, because you keep the freedom to choose your angle afterward. Files add up quickly. The camera’s internal memory can help in a pinch, but it doesn’t replace a proper card for a full day of shooting.

My tips before your first outing
- Format the card in the X6 before your first shoot. It’s the simplest way to start with the right file system.
- Avoid filling the card to 100%. Leave some headroom, especially before a long 8K sequence.
- Transfer your footage regularly to an SSD or a computer. 360° files take up space fast.
- Buy from Amazon or a reputable retailer. Counterfeit memory cards still exist, and they’re especially frustrating with a video camera.
- Bring a second card on an important trip. It’s often more practical than waiting for a full transfer.
Which card should you choose in the end?
The SanDisk Extreme 256GB remains my first choice: it matches the X6’s profile well and it’s easy to recommend without overthinking it. The Samsung PRO Plus is a good alternative, especially if the included USB reader is useful to you. Finally, the Lexar Professional 1066x offers a third solid V30 option.

Frequently Asked Questions
Can you use a 128GB microSD card with the Insta360 X6?
Yes, as long as it’s UHS-I, U3, and V30. That’s enough for short outings, but 256GB is more comfortable with 360° files.
Is a V60 card necessary?
No—V30 is the level to aim for with the X6. A V60 can cost more without bringing any useful benefit for this use.
Why is the camera refusing my microSD card?
First check the V30 rating, format the card in the camera, and make sure it isn’t a counterfeit. A worn-out or too-slow card can also be the cause.
