SanDisk 32GB microSDHC Class 4 Memory Card – SDSDQM-032G
The SanDisk 32GB microSDHC Class 4 card is a basic, entry-level storage card built for standard-definition and up to 720p HD video recording on older or budget smartphones, feature phones, and basic digital cameras. It delivers read speeds up to 20MB/s with a minimum sustained write speed of 4MB/s, sufficient for everyday photos, music, and lower-resolution video rather than Full HD or 4K recording. Despite its modest speed class, the card carries the same durability standards found across SanDisk’s range, rated shockproof to roughly 2,000Gs (equivalent to a ten-foot drop) along with resistance to water, temperature extremes, and X-rays. It’s commonly bundled with a microSD-to-SD adapter, letting it work in a standard full-size SDHC slot found in older laptops and cameras. At 32GB, this card suits buyers with basic devices needing straightforward extra storage rather than high-speed performance.

Best Suited For
- Budget or older smartphones and feature phones that support microSDHC but don’t require higher UHS speed classes
- Basic digital cameras and camcorders limited to standard-definition or 720p HD recording
- Buyers needing affordable, higher-capacity expansion storage for music, photos, and files without paying for speeds they won’t use
Recommended Action: Confirm your device’s video recording requirements before purchase — this Class 4 card supports up to 720p HD only and is not suited to Full HD or 4K recording, which need a higher-speed Class 10 or UHS-rated card.
