Before you choose
Will it work with my device?
Check for a microSDXC slot, support for your chosen capacity and the write-speed requirements in your device manual. Built-in storage alone does not mean a memory card can be added.
Is recording limited to 1080p?
Resolution alone does not determine compatibility. Recording depends on bitrate, required write speed and device recommendations. The 100 MB/s read rating is not a write speed; not every 2K or 4K mode is guaranteed.
How many days of footage can it hold?
Duration varies with bitrate, resolution, compression, audio and continuous or motion-triggered recording. With the same settings, 256GB provides roughly twice the capacity of 128GB; there is no fixed number of days.
What about continuous recording and warranty?
Ultra is a general-purpose range, not High Endurance. Check SanDisk's terms for surveillance, dash cams and continuous recording; manufacturer warranty coverage should not be assumed.
Usable capacity is lower after formatting. The card does not include a cloud subscription or another device.
