Best Memory Cards for Insta360 X4
The Insta360 X4 is an 8K30 360 camera with dual 1/2-inch sensors, a 200 Mbps bitrate ceiling, and no built-in storage. Insta360’s manual is clear on the slot: exFAT microSD, UHS-I, V30 or above, 1 TB max. The same page says do not use UHS-II, UHS-III, or cards larger than 1 TB — those fail recordings. There is no card in the box, and there is no 47 GB X6-style buffer. Official 8K30 High Bitrate is 1.5 GB per minute. The 2026 stick that matches that camera — and sits on Insta360’s own X4 tested table — is the SanDisk Extreme PRO 256GB UHS-I microSDXC (SDSQXCD-256G). It is not a Samsung EVO Select, and it is not a UHS-II V60.

Street prices move. V30 is 30 MB/s (240 Mbps). X4’s ceiling is 200 Mbps; official 8K30 High Bitrate is 1.5 GB/min. A 256 GB card is ~170 minutes of that mode before the 1–2 GB cache Insta360 tells you to leave free — longer than the 75-minute 8K30 battery. Format in the camera. There is no internal spare tire.
How We Picked These Cards
- What Insta360 published: X4: dual 1/2-inch sensors, 8K 7680×3840 at 30/25/24 fps, 5.7K at up to 60 fps, 4K 360 at up to 100 fps, ~72 MP 360 stills (11904×5952). 360 files are INSV; single-lens is MP4. Max video bitrate 200 Mbps. Weight 203 g. USB Type-C 3.0. 10 m waterproof. 2290 mAh; 135 min at 5.7K30, 75 min at 8K30 (lab). No built-in user storage. Manual + storage FAQ: exFAT microSD, UHS-I, V30 or above, 1 TB maximum. “Do not use UHS-II/UHS-III … or memory cards larger than 1TB.” File-size table: 8K30 High 1.5 GB/min, 8K30 Standard 1 GB/min, 5.7K30 High 700 MB/min, 5.7K30 Standard 500 MB/min, plus 1–2 GB cache. Troubleshooting: prefer 128 GB or larger; 32/64 GB are more likely to throw insufficient-speed warnings. Format in the camera or the Insta360 app. No card in the bundle.
- What the slot has to swallow: 200 Mbps is 25 MB/s. V30’s 30 MB/s floor covers it. 8K30 High at 1.5 GB/min fills 256 GB in about 2.8 hours of rolling, but the battery dies at ~75 minutes — so 256 GB is one 8K outing with dump room, not a “needs 1 TB” argument. 5.7K60 is the smoother mode; it is not a faster bus. USB 3.0 can dump; a UHS-I reader still wins on a full card of INSV. Wi-Fi is not a 256 GB path.
- The box you actually buy: X4 user-manual tested table (third-party): SanDisk Extreme V30 A2 SDSQXAV-256G, SDSQXA1-512G, SDSQXA1-1T00; Extreme PRO V30 A2 SDSQXCD-256G, SDSQXCZ-512G, SDSQXCD-1T00; Lexar 1066x SILVER LMS1066256G / LMS1066512G. Current Extreme PRO 256 is still SDSQXCD-256G-GN6MA (200/140). Current Extreme 256 is SDSQXAV-256G-GN6MA (190/130). Lexar 1066x 256 remains LMS1066256G-BN. Skip SDSQXAO Nintendo Extreme. Skip EVO Select as the default — it is not on that X4 table. Skip two-row UHS-II.
Best Memory Cards for Insta360 X4: Detailed Reviews
SanDisk Extreme PRO 256GB UHS-I microSDXC View on Amazon View on B&H
| SKU | SDSQXCD-256G-GN6MA (X4 manual lists this 256 GB Extreme PRO). One row of pins. |
|---|---|
| Class | UHS-I · U3 · V30 (30 MB/s floor) · A2 · Class 10 |
| SanDisk sheet | Up to 200 MB/s read · 140 MB/s write on 256 GB–2 TB Extreme PRO microSD |
| On X4 | 200 Mbps ceiling is 25 MB/s. V30 is the class. 256 GB ≈ 170 min of official 8K30 High before cache — past the 75 min battery. |
| Buy this listing | Extreme PRO microSD UHS-I. Not Extreme PRO UHS-II SD. Not 1 TB unless you want Layer 2. |
Why it fits the X4. This body will not record without a card. Insta360 already printed SDSQXCD-256G on the X4 compatibility table. 8K30 High at 1.5 GB/min plus 1–2 GB of cache is why 64 GB is a trap and 256 GB is the default. Format to exFAT in the camera. Pull the card or use USB 3.0 / Quick Reader. The 200 MB/s read is a reader spec; the camera writes to the V30 floor. Thermo Grip Cover is for 8K heat, not for a faster card.
Skip this if Extreme 256GB is a few dollars cheaper this week — same list, same 256 GB. Skip it if you will not dump for days — 1 TB. Skip two-row UHS-II listings that reuse the Extreme PRO name.
- Printed on the X4 tested table
- 256 GB outlasts one 8K30 battery at 1.5 GB/min
- 1 TB sibling (SDSQXCD-1T00) is also on that table
- Costs more than Extreme at the same capacity
- Peak 140 MB/s is not a UHS-II bus the X4 has

SanDisk Extreme 256GB UHS-I microSDXC View on Amazon View on B&H
| SKU | SDSQXAV-256G-GN6MA. X4 manual: SDSQXAV-256G-GN6GN class Extreme 256 V30 A2. Same family, one row of pins. |
|---|---|
| Class | UHS-I · U3 · V30 · A2 · Class 10 |
| SanDisk sheet | 256 GB–1 TB Extreme: up to 190 MB/s read · 130 MB/s write. V30 min 30 MB/s. |
| SKU trap | SDSQXAO Nintendo Switch Extreme. Extreme PRO. Full-size Extreme SD. EVO Select sold as “the same thing.” |
Why it is Value, not Overall. Insta360 listed Extreme 256 on the X4 table. The slot does not get faster because the box says PRO. You keep V30 on UHS-I and 256 GB. You give up 10 MB/s of SanDisk’s peak-write sticker. That is a reader argument, not an 8K30 argument. Format in the camera. Do not buy the Switch-licensed Extreme if the photo is a Nintendo card.
Skip this if Extreme PRO 256 is within a few dollars — Overall. Skip 128 GB Extreme as the only card if 8K30 High is the mode you paid for (≈85 minutes at 1.5 GB/min, then you are in the cache warning).
- On the X4 tested list (SDSQXAV)
- Same 256 GB / V30 story as Overall
- Slightly slower SanDisk peak write than PRO
- Easy to grab a Switch Extreme by mistake

Lexar Professional 1066x 256GB microSDXC View on Amazon View on B&H
| SKU | Lexar Professional 1066x SILVER UHS-I · LMS1066256G-BN (256 GB). 512 GB LMS1066512G is also on the X4 list. |
|---|---|
| Class | UHS-I V30. Typical pack: ~160 MB/s read / ~120 MB/s write. |
| On X4 | Same UHS-I V30 request as SanDisk. Format in the camera. Not a UHS-II card. |
| SKU trap | 64 GB 1066x (on the table, but Insta360 also says 32/64 trigger speed warnings). Lexar PLAY. Gold UHS-II. |
Why it fits the X4. Insta360 already tested this 256 GB SKU on this body. You are not gambling on EVO Select. 256 GB is the size that matches 1.5 GB/min plus a 75-minute 8K battery. Confirm SILVER / 1066x / V30 on the face. ONE X2 had a Lexar warning; the X4 printed table is why this row exists.
Skip this if Extreme 256GB is the same price — Value. Skip 64 GB 1066x as the only card.
- On Insta360’s X4 tested 256 GB list
- UHS-I V30 without SanDisk branding
- Slower peak read than Extreme PRO for laptop dump
- Easy to buy the 64 GB listing

If You Need Something Else
These two are not cheaper versions of the Top 3. One is the 1 TB ceiling Insta360 printed for X4. One is the EVO Select the old page sold as a hero.
SanDisk Extreme PRO 1TB UHS-I microSDXC View on Amazon View on B&H
| SKU | SDSQXCD-1T00-GN6MA on the X4 tested table. Still UHS-I V30 / A2, one row of pins. Extreme 1TB SDSQXA1-1T00 is the non-PRO sibling on the same table. |
|---|---|
| On X4 | Family max. Same V30 as 256 GB. About 11 hours of official 8K30 High (1.5 GB/min) before cache — many 75-minute batteries, not a faster slot. |
| When it wins | Multi-day 8K, no laptop, or you refuse to dump until the Thermo Grip is in the bag |
Insta360’s rule is 1 TB, not 2 TB. Extreme PRO microSD now exists at 2 TB on SanDisk’s sheet; that is the skip. Format in the camera. A full terabyte of INSV is a reader job.
Skip this if you dump every evening — 256 GB Extreme PRO or Extreme.

Samsung EVO Select 256GB microSD View on Amazon View on B&H
| Why it shows up | The 2025 page called EVO Select Top Choice. The April 2026 singular-slug page used it as Value. Typical packs are UHS-I V30. |
|---|---|
| On X4 | Not on Insta360’s printed X4 tested table. V30 may record. This page defaults to SKUs Insta360 already listed: Extreme, Extreme PRO, Lexar 1066x. |
| Same skip | UHS-II V60 “premium,” 2 TB microSD, Kingston Canvas Go as the only card, 32/64 GB V30 as the 8K stick. |
If an EVO Select already lives in the camera and 8K30 High is finishing clips, keep using it until you replace it. Do not buy it as the X4 card when Extreme 256 and Lexar 256 are on the official list at the same street prices.
Skip this if the camera is an X4 and you are buying one card. Buy Extreme PRO 256GB, Extreme 256GB, or Lexar 1066x 256GB.

Frequently Asked Questions
What speed class the X4 needs
Insta360: UHS-I microSD, V30 or above, exFAT, 1 TB max. V30 is 30 MB/s (240 Mbps). The camera’s maximum bitrate is 200 Mbps (25 MB/s). Official 8K30 High Bitrate is 1.5 GB/min. Class 10 with no V30 is the skip. A2 is a phone-app rating, not the X4 requirement.
Why not a UHS-II V60 card
X4 storage FAQ: do not use UHS-II or UHS-III. Those cards are not compatible and may cause recording issues. The extra row of pins is for a UHS-II reader, not this slot. 200 Mbps does not unlock a second bus.
The X4 has no internal storage
Correct. Unlike X6 (64 GB flash / 47 GB usable), the X4 will not start an 8K clip without a card. Put a formatted V30 in before the first outing. Insta360 also wants 1–2 GB free for recording cache — a “full” 64 GB card is why recordings die early.
256 GB, 512 GB, or 1 TB
256 GB is the default: one 75-minute 8K30 battery at 1.5 GB/min still leaves dump room. 512 GB (Extreme SDSQXA1-512G / Lexar LMS1066512G / Extreme PRO SDSQXCZ-512G) is extra days, same V30. 1 TB is the printed maximum (Extreme PRO SDSQXCD-1T00). Over 1 TB is the skip. A bigger card does not raise UHS-I V30. Format in the X4. Insta360: 32/64 GB cards are more likely to show insufficient speed — do not buy those as the 8K card even if they are V30.
Final Verdict
For most Insta360 X4 kits, buy a SanDisk Extreme PRO 256GB UHS-I, format it in the camera, and stay on UHS-I V30. There is no internal storage. 8K30 High is 1.5 GB/min and 200 Mbps — not a UHS-II problem. Same 256 GB for less? Extreme 256GB. Same list, other brand? Lexar 1066x 256GB. A week without dumping? Extreme PRO 1TB. Skip EVO Select as the default, skip 32/64 GB, skip 2 TB, skip X5/X6 shopping lists on this URL. The camera never shipped a card. V30 UHS-I is the slot.
