Upgrade to the SanDisk Extreme microSD if you need V30-rated write speeds for 4K video; stick with the Ultra for photos and casual use where price is the priority.

Frequently Asked Questions

What SD Card Do I Need for Holy Stone HS720 / HS720E / HS720G?
The Holy Stone HS720 / HS720E / HS720G takes a microSD card rated Class 10 / U1 (V30 recommended for HS720G) or faster. 32GB or 64GB or 128GB covers most owners, and the maximum is 128GB. Buy SanDisk, Lexar, Samsung or Kingston from a reputable seller: counterfeit cards are the most common cause of lost files.
Why isn't my HS720 saving photos to the card?
Check capacity and format. Use a card no larger than 128GB, formatted FAT32 (or exFAT on the HS720G). On the original HS720, try a 32GB card.
Is V30 required for Holy Stone HS720 / HS720E / HS720G?
Yes. V30 guarantees 10-30 MB/s of sustained write, which keeps the Holy Stone HS720 / HS720E / HS720G free of dropped frames, clips that stop early, or corrupted files. Faster cards work too.
What size SD card should I get for Holy Stone HS720 / HS720E / HS720G?
32GB covers light use; 128GB suits heavy use. The maximum is 128GB.
Can I use older or slower cards with Holy Stone HS720 / HS720E / HS720G?
Not below Class 10 / U1 (V30 recommended for HS720G). Slower cards cause dropped frames, clips that stop early, or corrupted files. Check the card label for the Class 10 / U1 (V30 recommended for HS720G) mark.
Does the brand matter for Holy Stone HS720 / HS720E / HS720G?
Yes. SanDisk, Lexar, Samsung and Kingston cards meet their rated speeds. Buy from the brand's store or a major retailer: counterfeit cards sold under those names are common on marketplaces.
What happens if I use the wrong card with Holy Stone HS720 / HS720E / HS720G?
A card slower than Class 10 / U1 (V30 recommended for HS720G) causes dropped frames, clips that stop early, or corrupted files. A card over the maximum capacity or in the wrong format may not be recognized.
How long will an SD card last in Holy Stone HS720 / HS720E / HS720G?
Several years in normal use. Cards usually fail from wear or counterfeit flash, not age. Replace yours at the first write error, corrupted file or "card not recognized" message.
