V30 is 30 MB\/s. Insta360\u2019s X6 bitrate ceiling is 360 Mbps (~45 MB\/s); typical 8K 360 video on the X-series table is 240 Mbps, which is exactly the V30 floor. A second row of UHS-II pins does not raise that floor in this body \u2014 Insta360 says those cards can stop the recording. Format in the camera. 47 GB internal is the spare tire.<\/p>\n\n<h2>How We Picked These Cards<\/h2>\n<ul>\n  <li><strong>What Insta360 published:<\/strong> X6: dual 1\/1.1-inch sensors, native 8K 7680\u00d73840 at 50\/48\/30\/25\/24 fps, 6K at up to 60 fps, 4K 360 at up to 100 fps, 16K timelapse 15360\u00d77680, 120 MP 360 stills. Video is H.265; 360 files are INSV, flat is MP4. Maximum video bitrate 360 Mbps. 64 GB built-in (47 GB available). Slot: microSD, UHS-I V30 or higher. USB Type-C 3.1. 196 g. 20 m waterproof. Endurance mode: 140 min at 8K30. No memory card in the bundle. Support: use UHS-I V30 or above, exFAT; do not use UHS-II, UHS-III, or cards larger than 1 TB \u2014 \u201cnot compatible and may cause your recording to fail.\u201d Quick Reader follows the same 1 TB \/ UHS-I rule.<\/li>\n  <li><strong>What the slot actually has to swallow:<\/strong> V30 is a 30 MB\/s sustained-write floor (240 Mbps). That matches Insta360\u2019s \u201cother 360 video modes: 240 Mbps\u201d row on the X-series spec table; the 360 Mbps number is the camera maximum (16K timelapse sits there). Variable H.265 is not a constant 1.8 GB\/min, but 8K still fills 47 GB of internal storage in a short outing. 256 GB is the default so one card outlasts a 140-minute 8K30 battery, not because a bigger card writes faster. USB 3.1 can dump; a UHS-I reader still wins on a full 256 GB of INSV. Format in this camera.<\/li>\n  <li><strong>The box you actually buy:<\/strong> Extreme PRO microSD 256GB SDSQXCD-256G-GN6MA: UHS-I, U3, V30, A2, SanDisk up to 200 MB\/s read \/ 140 MB\/s write (256 GB\u20132 TB class).

V30 is a 30 MB\/s sustained write (240 Mbps). The camera\u2019s maximum bitrate is 360 Mbps; typical 8K 360 video on the X-series table is 240 Mbps. Format exFAT in the camera. Class 10 with no V30 is the skip. A2 is a phone-app rating; nice on the face, not the X6 requirement.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Why not a UHS-II V60 card for 360 Mbps?<\/h3><p>Insta360\u2019s storage note: do not use UHS-II or UHS-III microSD. Those cards are \u201cnot compatible and may cause your recording to fail.\u201d The extra row of pins is for a UHS-II reader, not this slot. The old page sold ProGrade V60 as Premium. That is the wrong default on an X6.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Is 47 GB of internal storage enough without a card?<\/h3><p>Enough to start recording if the card is in the bag. Not enough for the 8K you bought the camera for. 64 GB flash, 47 GB usable. At ~1 GB\/min of 8K30 (third-party measurement) that is under an hour; at a 240 Mbps ceiling it is much less. The bundle still ships no microSD. Put a 256 GB V30 in before the first 140-minute endurance run.<\/p><\/div>\n  <div class=\"faq-item\"><h3>256 GB, 512 GB, or 1 TB?<\/h3><p>256 GB is the default on this page: one card, one 8K30 battery, dump at the laptop. 512 GB is extra room, same V30. 1 TB is Insta360\u2019s printed maximum (Extreme PRO SDSQXCZ-1T00 is on the tested list).
