Best MicroSD Card for Godox C100 Mini Camera
The Godox C100 Mini (Transparent Viewfinder Camera) has no internal memory. Godox’s own sheet is a TF / microSD slot and a hard ceiling: up to 128 GB. Stills are a ~2 MP, 1920×1080 crop; video is 1080p at ~29.97 fps with a 20-minute clip stop. USB is 2.0. FAT32 or exFAT. The 2026 card is a 128 GB SanDisk Extreme microSDXC — the official max, UHS-I, empty when it goes in. It is not a 256 GB V90 sold for a camera Godox already capped at 128.

How We Picked These Cards
- What Godox published: C100 Transparent Viewfinder Camera (godox.com/product-e/C100): built-in TF card slot, supports up to 128 GB; USB 2.0 data; USB-C charge 5 V / 1 A; battery >1.5 h continuous shooting; ~65 g; transparent screen >50%. Independent sheets that match the box: ~2 MP stills (1920×1080 native, 16:9 / 4:3 / 3:2 / 1:1 crops), video 1920×1080 at ~29.97 fps, ~20-minute clip limit, FAT32 / exFAT, no built-in storage, no Wi-Fi app — OTG over the same USB-C. Center 25% meter is a film-companion feature, not a card feature.
- 128 GB is a ceiling, 1080p is a Class 10 job: Godox did not print a V class. 1080/30 on a 2 MP encoder is well under a Speed Class 10 / U1 floor (10 MB/s). V30 is cheap insurance and a card you can later drop in a phone; it is not required for this bitrate. V90 / UHS-II pins are unused. USB 2.0 is ~30–40 MB/s in the real world — Extreme’s 200 MB/s read is a computer-reader number, not a C100 cable number. A 256 GB card is past the published max; do not “try it.”
- The box you actually buy: A dedicated microSDXC, 64 or 128 GB, Class 10 minimum, formatted empty (FAT32 or exFAT) before first insert. Extreme 128 GB UHS-I (V30). Ultra 128 GB or 64 GB. Not Extreme PRO V90. Not a 256 GB Extreme. Not the Switch / dash-cam card that still has folders on it — mixed contents are the reported way the C100 “takes” a frame and writes nothing. The green LED that keeps flashing is the card check, not a style light.
Best MicroSD Card for Godox C100 Mini Camera: Detailed Reviews
SanDisk Extreme 128GB microSDXC View on Amazon View on B&H
| Model | SanDisk Extreme microSDXC UHS-I · 128 GB (not 256 GB) |
|---|---|
| Class | V30 / U3 / Class 10 — above 1080p30, still UHS-I |
| On C100 | 2 MP JPEG + 1080/29.97 · 20 min clips · USB 2.0 offload |
| Format | FAT32 or exFAT, empty. This camera is not a dump for a phone DCIM |
| Buy this listing | Extreme 128 GB microSD. Not Extreme 256. Not Extreme PRO. Not Extreme SD (full-size) |
Why it fits the C100 Mini. Godox sold “up to 128 GB” as the storage story. Extreme 128 GB is that number on a card that is still UHS-I. V30 is unused by the 1080p encoder and useful if the same card later sits in a phone; the pairing reason to buy Extreme over Ultra is not 4K — it is a known 128 GB SKU you can reorder and a write floor that will not flake on a 20-minute clip. The C100 has no playback screen and no “card inserted” icon. A dedicated, empty Extreme means the green LED is not your first clue that yesterday’s GoPro folder confused the writer. USB-C to a phone is USB 2.0; pull the card if you want Extreme’s read speed on a real reader.
Skip this if you want the same 128 GB at Class 10 money — Ultra 128. Skip 256 GB Extreme in the same search row.
- Hits the official 128 GB max
- UHS-I V30, not a UHS-II tax
- Easy to keep as the only files on the card
- V30 is spare for 1080p30
- USB 2.0 will not show the read sticker

SanDisk Ultra 128GB microSDXC View on Amazon View on B&H
| Model | SanDisk Ultra microSDXC · 128 GB |
|---|---|
| Class | Class 10 / U1 (A1 on many boxes is a phone badge — unused here) |
| On C100 | Same 2 MP / 1080p30 / 20 min math as Extreme. Write floor is the Class 10 line |
| OTG | USB 2.0 to a phone. Ultra’s lower read claim does not matter on that cable |
| SKU trap | Ultra 128 GB full-size SD. Ultra 32 GB. High Endurance dash-cam cards as “more reliable” |
Why it is Value. The C100 is a 2 MP toy-companion with a light meter, not an R5. Ultra 128 GB is the official capacity at the speed class 1080p30 has used for a decade. You give up Extreme’s V30 sticker and keep a card that still fills Godox’s 128 GB sentence. Format empty. Do not use High Endurance / Max Endurance dash-cam cards as a “tougher” C100 card — those are 24/7 write products; this camera is 1.5 h and a shutter button.
Skip this if you already decided 64 GB matches the battery — Ultra 64. Skip if you want one Extreme SKU in the bag.
- 128 GB = Godox max without V30 money
- Class 10 is the 1080p30 floor
- Same empty-card rule as Extreme
- Slower sequential write than Extreme
- A1 on the label is phone marketing

SanDisk Ultra 64GB microSDXC View on Amazon View on B&H
| Model | SanDisk Ultra microSDXC · 64 GB |
|---|---|
| Why 64 not 128 | Battery >1.5 h continuous · clips stop at 20 min · 2 MP files are small |
| On C100 | Still at or under the 128 GB cap. Same FAT32 / exFAT empty format |
| Buy this listing | Ultra 64 GB microSDXC. Not a 64 GB full-size SD for an adapter |
| Skip | 16 / 32 GB extras, no-name 64 GB with no Class 10 print |
Why it is Budget. A 2 MP JPEG is a megabyte-class file. A 20-minute 1080p clip is a couple of gigabytes, not a CFexpress hour. 64 GB Class 10 outlasts the claimed battery. Buy this if the C100 is a film-meter that sometimes records, not a week-long diary. Same dedicated-card rule: do not split it with a phone.
Skip this if the card stays in for a month of blind shooting — Ultra or Extreme 128.
- Class 10 under the 128 GB cap
- Matches a 1.5 h charge
- Cheapest honest SanDisk microSDXC
- Half of Godox’s published max
- You will dump more often than 128 GB

If You Need Something Else
These two sit in the same Amazon row as “best microSD.” One breaks Godox’s 128 GB sentence. One is a video-class tax for a 2 MP camera.
256 GB and larger microSD View on Amazon View on B&H
| Godox sheet | TF slot · supports up to 128 GB |
|---|---|
| 256 / 512 / 1 TB | Past the published max. Do not treat “it might work” as a spec |
| What to buy instead | Extreme or Ultra 128 GB |
Godox did not write “up to 1 TB.” They wrote 128 GB. A 256 GB Extreme in the same color sleeve is the wrong SKU for this slot. If a listing is 200 GB or 256 GB because the 128 is out of stock, wait or buy Ultra 64. The C100 also has no card icon — a card it cannot mount looks like an empty camera.
Skip this if the body is a C100. That is the whole pairing.

SanDisk Extreme PRO V90 View on Amazon View on B&H
| What the box sells | V90 · high sustained write · 4K / 8K / cinema cameras |
|---|---|
| What the C100 is | ~2 MP · 1080/29.97 · 20 min clips · USB 2.0 |
| What you get | A Class 10 card at cinema prices |
V90 is a 90 MB/s video floor. This camera is a 1080p30 toy-companion and a center-weighted meter for film. Extreme PRO V90 is the UHS-II / HX move: a spring for a heavier panel. Keep V90 for a camera that prints 4K on the box.
Skip this if the camera is a Godox C100 Mini. Buy Extreme 128 or Ultra 128.

Frequently Asked Questions
What is the largest card the C100 takes?
Godox: up to 128 GB in the TF / microSD slot. That is the max, not a starting point. 256 GB is a skip.
Do I need V30 or A2?
No. 1080p30 and 2 MP JPEGs sit on Class 10 / U1. V30 on Extreme 128 is optional headroom. A2 is a phone app-class badge. USB 2.0 will not show a 200 MB/s read.
How should I format the card?
FAT32 or exFAT, empty. Do not drop in a card that still has another camera’s folders. Reviewers lost frames that way even when the filesystem was “correct.” If the green LED keeps flashing, reseat the card and check format.
Does the C100 have built-in storage?
No. No card means no files. There is also no “card inserted” icon on the transparent HUD — check the slot before you walk out.
Final Verdict
For a Godox C100 Mini, buy a dedicated microSDXC that is 128 GB or less, Class 10 or faster, formatted empty. The default is a SanDisk Extreme 128 GB so you sit on Godox’s published max. Want the same 128 without V30? Ultra 128. Want battery-sized storage? Ultra 64. Skip 256 GB. Skip V90. Skip a phone card with folders. The slot is TF. The ceiling is 128 GB. The files are 2 MP and 1080p.
