To illustrate, microSD card speed using ‘The Tortoise And The Hare’. A fable most of us know by heart. And if we don’t know the story, then we at least know the lesson. The tortious appeared slow, but he was steady. The hare was fast, but he wasn’t consistent. In the end, the tortoise won the race because he didn’t slack off like the hare. It was a life lesson illustrating the payoff of persistence and consistency versus the consequences of slacking off and underestimating.
The market today’s populated with numerous microSD cards, all clocked at various speeds. Most consumers look at these memory cards and feel like they’re reliving The Tortoise And The Hare, but the question is whether or not faster really is better when it comes to these handy flash storage devices?
The Choice of Performance.
Different types of flash memory are used by different manufacturers to create SD memory cards. Therefore, the actual transfer speed of each card by each manufacturer can vary. As a result, it’s difficult to determine which microSD cards will provide reliable speeds. Is performance diminishing? In short, you need eProvided for micro SD recovery service. Over time micro SD cards decrease in size and speed.
We use SD cards in mobile devices. They range from cell phones to handheld video recorders to digital cameras. The speed of a card becomes particularly important when taking video because it affects the smoothness of the playback. When picking a microSD card, the speed of the card you choose is your choice of performance.
SD Association microSD Card Speed Classes.
Higher isn’t always better. According to the SD Association, speed classes designate the minimum writing performance. Use higher end speed class cards when shooting high resolution 4K video. 4k video production recordings save much more data.
microSD Card Speed Classes list.
They have identified seven speed classes:
- Class 2 Speed Class
- Class 4 Speed Class
- Class 6 Speed Class
- Class 8 Speed Class
- Class 10 Speed Class
- Class 1 UHS Speed Class
- Class 3 UHS Speed Class
When looking at microSD card speed and the competition, the first question you need to ask yourself when it comes to speed is how much you’ll need. Certain file types, such as HD videos, require a minimum writing speed to guarantee smooth video playback.
Each class roughly corresponds to the minimum writing speed of the card in MB/s (megabytes per second). Therefore, a Class 2 microSD memory card has a minimum writing speed of 2MB/s, a Class 4 has a minimum writing speed of 4MB/s, etc. HD videos require a minimum of a Class 4 card.
Compatibility Is Important.
When choosing a microSD card, compatibility is vital to consider. Not all SD cards work across all devices, and it’s important to consider the BUS speed of the device you’ll be interfacing the SD card with. Why? Because your microSD card could be “insta-fast,” but if the BUS of the device you’re interfacing with can’t keep up, all of that super speed’s wasted.
The standard SD card is slower than the SDHC and SDXC cards. The SDXC offers the highest speeds and the lowest compatibility. The SD card is the slowest but most widely compatible card, followed closely by the SDHC & SDXC. it is best to use faster microSD cards. Above all, slower SD cards can become overheated and fail. In the event they do fail, eProvided will recover lost data on your microSD card.
Why microSD Card Speed is Crucial.
At the end of the fable, it wasn’t speed that won the race for the tortoise; it was consistency. When it comes to SD cards, speed is important to a degree. The faster the file transfer speed, the less risk there is of corruption or malfunction. However, the importance requires a balance. Your file transfer speed will only be as fast as the slowest BUS speed. When choosing your microSD card, be sure to choose the one that is most consistent with your devices. It will provide the best possible interface, ensuring you’re not too fast or too slow, but running at just the right speed to win your data race.
