SD cards
The SD card is EGO1's offline storage. Card choice matters: the microSD/TF market is full of counterfeit and low-grade cards, and a fake or incompatible card will cause the device to fail to recognize it or to not record at all.
Requirements
| Property | Requirement |
|---|---|
| Format | FAT32 |
| Capacity | ≤ 128 GB recommended |
| Speed class | At least A1 and V30 (A2 / V60 / V90 are fine) |
| Quality | Genuine card from a reputable seller |
Choosing a card
- Use a card rated at least A1 and V30 — these classes sustain the write speed needed for dual 1080p H.265 streams. Higher classes (A2, V60, V90) are fine.
- A card below that class may be too slow and fail to record even if it mounts.
- Buy from reputable sellers. Counterfeit and low-grade cards are common and may not be recognized, or may drop data mid-recording — verify a new card before relying on it (see below).

Formatting
Format the card as FAT32 before first use. Use your operating system's disk utility, or a dedicated FAT32 formatter such as the SD Association's official SD Card Formatter (most OSes only offer FAT32 in the built-in tools for cards up to 32 GB, so a dedicated formatter is handy for 64–128 GB cards).
Inserting and removing
Insert and remove the SD card only while the device is unpowered. After copying recordings to your computer, delete the exported files from the card to free space for the next session — see Retrieve & view data.
