Transcend 32GB 300S UHS-I U1 SDHC Memory Card

Capacity and compatibility

The Transcend 32GB 300S is an SDHC memory card built for UHS-I compliant cameras and camcorders. Its 32GB capacity stores thousands of high-resolution photos and hours of Full HD video. It targets photographers and videographers who need reliable removable storage for daily shoots. Buyers who want more storage than 32GB or require UHS-II speeds should look at higher-capacity or faster-tier cards.

Sustained write behaviour

The card delivers a maximum read speed of 95MB/s for quick file offloads to a computer. The U1 speed class guarantees a minimum sequential write of 10MB/s, which supports continuous Full HD recording without dropped frames. Under prolonged heavy use the write rate stays at or above that class floor rather than peaking briefly and throttling. Users needing sustained write speeds above 10MB/s for higher-bitrate formats will need a card with a higher speed class rating.

Durability upgrades

This model replaces standard cards that lack environmental hardening. It meets JIS IPX7 waterproofing for 30 minutes at 1 metre depth and operates from -25°C to 85°C. Static protection follows IEC61000-4-2 and X-ray immunity follows ISO7816-1, adding safety during travel and handling. The jump is worth it for creators who shoot outdoors, travel frequently or work in harsh conditions where unprotected cards risk data loss.
