Transcend 300S microSDHC Memory Card 32GB, UHS-I U1 A1 Class 10, with SD Adapter, for Phones, Tablets and Cameras

The Transcend 300S microSDHC 32GB with SD adapter (TS32GUSD300S-A) is a UHS-I U1, Class 10, A1 memory card for phones, tablets, cameras and handheld consoles that need dependable storage for photos, apps and Full HD video.

The included adapter lets the same card work in full-size SD slots on cameras and laptops. Transcend publishes speed only for the whole 300S series, not for the 32GB card, so this page lists the guaranteed U1 and A1 minimums instead of a headline figure.

• 1 × Transcend 300S microSDHC 32GB card
• 1 × microSD-to-SD adapter

• Formatted capacity is lower than the nominal 32GB — part of the space is used by the file system and the card firmware, so your device will show slightly less.
• The UHS-I U1 A1 Class 10 rating guarantees at least 10 MB/s sustained write — enough for photos and Full HD (1080p) video recording.
• A1 (App Performance Class 1) means minimum random performance of 1,500 read / 500 write IOPS, so it works well as extra storage for apps on Android phones and tablets.
• SDHC cards use FAT32, which limits a single file to 4 GB — most cameras simply split long recordings into several files.
• With the included SD adapter the same card also works in cameras and laptop SD slots.

• Very old SD-only devices (that accept up to 2 GB cards) cannot read SDHC.
• 4K cameras, drones or action cams that require a U3 or V30 card — this card is rated for Full HD, not 4K recording.
• UHS-II speeds — this is a UHS-I card; it works in UHS-II devices but only at UHS-I speed.
• 24/7 recording in dashcams or CCTV cameras — Transcend does not rate this card as a high-endurance model; choose an endurance-rated card for continuous recording.
