What Is Memory Card Speed
Below is a MRR and PLR article in category Computers Technology -> subcategory Hardware.
Understanding Memory Card Speed
In recent years, the range and variety of flash memory cards have expanded dramatically. Since the introduction of the first 4MB flash memory card, numerous formats and speed options have emerged, especially for digital cameras and other devices. This abundance can easily overwhelm the average consumer.
Memory Card Formats and Speed Ratings
Memory cards come in different shapes and sizes, like Secure Digital (SD), Compact Flash, and Memory Stick, each with various speed ratings. The speed of a memory card indicates how fast data can be transferred to or from it. This is often represented by 'Times' ratings (e.g., 12X, 40X) or in megabytes per second (MB/s).
Here's a quick conversion chart:
- 8X = 1.2 MB/s
- 12X = 1.8 MB/s
- 20X = 3.0 MB/s
- 25X = 3.8 MB/s
- 30X = 4.5 MB/s
- 40X = 6.0 MB/s
- 60X = 9.0 MB/s
- 66X = 10.0 MB/s
- 80X = 12.0 MB/s
- 90X = 15.0 MB/s
- 133X = 20.0 MB/s
Why Is Speed Important?
The need for different card speeds arises from advancements in digital devices. Higher resolution cameras and enhanced multimedia capabilities generate larger amounts of data, which requires faster cards for efficient storage and transfer. For instance, using a high-megapixel camera with a slow card can result in noticeable lag between shots due to slow write speeds.
Who Benefits from High-Speed Cards?
Professional photographers and enthusiasts using digital SLRs should opt for high-speed cards, ideally 40X or faster, especially if the camera resolution exceeds three megapixels. For compact cameras under three megapixels, standard cards of 12X or more should suffice.
Devices like digital camcorders and MP3 players also gain from faster memory cards. While high-speed cards were once beneficial mainly to professionals, they are increasingly essential for the latest PDAs, cameras, phones, and other mobile devices.
Older devices might not show a noticeable performance increase with high-speed cards due to their limited speed capabilities. It's important to remember that both the card and the device have maximum speed ratings, and performance will match the slower of the two.
Choosing the Right Card
When purchasing a memory card, consider your device's capacity and compatibility. Manuals often fail to specify the ideal speed rating, typically pushing their brand instead. If your camera has fewer than three megapixels, the card speed is less critical. For modern cameras, choose faster cards if speed is a priority.
Most mobile phones, PDAs, and satellite navigators work well with standard speed cards, though newer models might benefit from speeds up to 60X.
For reliable information, refer to the manufacturer's website or trusted review sites, as forums and retailers might not always provide the best guidance.
