The measurement of the SD Memory Card was carried out on Windows. Similar read and write speeds could certainly be achieved with the SD Memory Card under Linux and MacOS. Of course, the correct hard drive driver should be installed and the correct interface for the SD Memory Card should be used.
An SD ​​Memory Card (Secure Digital Memory Card) is a portable storage device that is widely used in various electronic devices. SD cards are known for their versatility, portability and ease of use. Here is a comprehensive description of SD memory card, including its technical details, features and applications:
Technical Details:
1. Formats:
- Standard SD: The original SD card, offering up to 2GB of storage.
- SDHC (Secure Digital High Capacity): Extends capacity from 4GB to 32GB.
- SDXC (Secure Digital Extended Capacity): Offers storage from 32GB to 2TB.
- SDUC (Secure Digital Ultra Capacity): The newest type of SD card, offering storage from 2TB to 128TB.
2. Interfaces:
- SATA (Serial ATA): Some SD cards can be used in devices with SATA interfaces, using the SATA II or III standard.
- USB (Universal Serial Bus): Many SD cards connect via an SD card reader with a USB port.
- SDIO (Secure Digital Input Output): Allows SD cards to be used for purposes such as Wi-Fi or GPS, in addition to storing data.
3. Speed ​​Classes:
- Class 2: Minimum write speed of 2 MB/s.
- Class 4: Minimum write speed of 4 MB/s.
- Class 6: Minimum write speed of 6 MB/s.
- Class 10: Minimum write speed of 10 MB/s.
- UHS-I (Ultra High Speed ​​Phase I): Up to 104 MB/s read and write speeds.
- UHS-II (Ultra High Speed ​​Phase II): Up to 312 MB/s read and 260 MB/s write speeds.
- UHS-III (Ultra High Speed ​​Phase III): Up to 624 MB/s read and 624 MB/s write speeds.
- V30, V60, V90: Video Speed ​​Class that defines the minimum write performance for video recording in Full HD, 4K and 8K.
4. Physical Size:
- Standard SD: 32 mm x 24 mm x 2.1 mm
- Mini SD: 21.5 mm x 20 mm x 1.4 mm (rarely used)
- Micro SD: 15 mm x 11 mm x 1 mm (more compact version often used in mobile devices)
5. Storage Technology:
- NAND Flash: The memory cells that store the data are based on NAND flash memory technology, which distinguishes between SLC (Single-Level Cell), MLC (Multi-Level Cell), TLC (Triple-Level Cell) and QLC (Quad-Level Cell).
Features:
1. Portability: SD cards are compact, lightweight and easy to carry, making them ideal for use in portable devices.
2. Compatibility: SD cards are compatible in a wide range of devices, including digital cameras, smartphones, tablets, laptops, MP3 players and other electronic devices.
3. Expandable storage: They provide an easy way to expand the storage space of devices, especially those that do not have built-in storage or require additional storage.
4. Fast data transfer: Higher speed classes and UHS standards enable fast data transfer rates, which are critical for storing and retrieving large files and recording high-resolution video.
5. Energy efficiency: SD cards require little power, making them ideal for use in mobile devices that rely on battery power.
6. Security: Some SD cards support features such as password protection and data encryption to secure the stored data.
7. Robustness: Many SD cards are waterproof, shockproof and temperature resistant, which increases their reliability in a variety of conditions.
Scope of application:
1. Digital cameras: SD cards are widely used in digital cameras and DSLR cameras for storing photos and videos. Higher capacities and speed classes are particularly useful for capturing high-resolution images and Full HD/4K videos.
2. Smartphones and tablets: MicroSD cards offer a cost-effective way to expand the storage space of smartphones and tablets to store additional apps, photos, videos, and other data.
3. Laptops and computers: SD cards can be used in laptops and computers to provide additional storage space or to transfer data between different devices.
4. Video recording devices: Devices such as action cameras and drones often use SD cards to record high-resolution video, especially with UHS-II or V90 cards for high bit rates.
5. GPS devices: SD cards are used in portable GPS devices to store maps and route information.
6. Media Players: Some media players use SD cards to store music, videos, and other media content.
7. Data Transfer: SD cards are useful for quickly sharing data between different devices, especially in situations where an Internet connection is not available.
8. Security and Surveillance Cameras: In surveillance cameras, SD cards are used to store video recordings locally.
Conclusion:
The SD ​​Memory Card is a versatile and widely used storage medium used in a wide variety of electronic devices. With various formats, speed classes, and capacities, it offers a flexible and powerful solution to storage needs. Its portability, compatibility, fast data transfer, and robustness make it a preferred choice for everything from basic data storage to high-resolution video recording.
