The Transcend SDHC memory card with 4 GB capacity and Speed Class 10 is a flash memory module in SD format, designed for use in digital cameras, DV recorders, mobile phones, and other devices requiring high storage capacity and recording of high-resolution audio and video. The card belongs to the High Capacity (SDHC) series from Transcend and is specifically designed for applications requiring real-time recording without delay or data loss. Speed Class 10 ensures a minimum write speed sufficient for continuous recording of high-resolution video. The card supports the SD 3.0 specification, ensuring compatibility with modern devices.

SDHC memory card
The card is classified as SDHC (Secure Digital High Capacity), meaning it has a storage capacity between 4 GB and 32 GB. In this case, the capacity is exactly 4 GB, which is sufficient for many digital cameras and mobile phones to store several hours of video or thousands of photos. SDHC technology enables efficient data transfer and is widely used in the camera industry.

Speed Class 10
Speed Class 10 is a standard classification for SD cards, guaranteeing a minimum write speed of 10 MB/s. This specification is crucial for recording high-resolution video, as insufficient write speed can lead to interruptions or data loss. The card is therefore suitable for AV applications requiring continuous data streams.

Technology explained simply
The card uses MLC flash technology (Multi-Level Cell), where multiple bits are assigned to each memory cell. This allows for higher storage density compared to SLC technologies, making the card more cost-effective to produce. The SD 3.0 specification supports advanced features such as UHS-I (Ultra High Speed Interface), increasing maximum data transfer rates. The card is therefore designed for devices equipped with a UHS-I interface to fully utilize its performance.

Compatibility and accessories
The card is compatible with all devices supporting SDHC cards, including digital cameras, DV recorders, mobile phones, and other mobile devices. Support for the SD 3.0 specification ensures use in modern devices requiring higher speeds and advanced features.

Applications
The card is primarily intended for recording high-resolution video and audio in digital cameras, DV recorders, and mobile phones. Speed Class 10 ensures the card remains stable during continuous recording. The card is also suitable for use in other devices supporting SDHC cards, such as MP3 players or portable navigation systems.

Operational advantages
The card provides sufficient storage capacity for daily use and enables high-quality video recording without interruptions. The use of MLC technology ensures good cost-efficiency, while Speed Class 10 guarantees reliability in AV applications. The SD 3.0 specification enables fast data transfer, facilitating use in modern devices.

Installation and mounting
Installation is done by simply inserting the card into the corresponding SD slot of the device. No additional tools or software are required. The card is recognized immediately upon insertion into the device.
