The art of recording data dates back to the end of the 19th century, the cylinder phonograph being one of the earliest devices put together. Since then, the rampant propulsion of technology has revolutionized the process of data recording.




During World War II, both sides of the battlefield put all their mind and might in out-performing their opponent. While the military division put all their resources in building more destructive weapons, a different set of brains were on an oath to change history forever.




The invention of Z3 in 1941, the first fully digital, programmable computer, was a giant leap for mankind. Soon after, the MK II Colossi became the first fully electronic programmable computer. What started from there is a constant struggle to further enhance computing power and process more data simultaneously.




However, another dilemma was soon to emerge. Before scientists realized, the computers were running out of memory and that halted the workflow. 




It was 40 years later that Toshiba announced the first flash drive/memory stick for data storage, a predecessor of modern-day data storage devices. Flash memory cards have become a standard in portable devices, such as mobile phones, PDAs, media players, and almost everything portable enough to carry around.



What Is A Flash Memory Card?

Micro SD Card



For those interested in the technicalities and wanting to know how does flash memory work, know that there are different flash memory card types.  They are a type of digital media storage device relying on non-volatile semiconductor memory. A non-volatile component to memory cards allows long term storage of data possible even after disconnecting from a power source. The printed circuits use NAND flash, a particularly useful variant of the original flash memory card, that allows fast, repeatable, and reliable data recall. It is capable of withstanding digital bug infections (a.k.a. computer virus) and eliminates the need to constantly refresh the data on the memory card.




All Memory Cards Are Different

All memory cards are different – with varying types available in the market. They differ in multiple ways, on the basis of whether they cater to consumers or enterprises as well as on the basis of flash memory card cost, their size, their capacity, and what particular devices are they compatible with.




The most widely used type nowadays is the Secure Digital or SD card. Newer generations are smaller in size, making them more versatile in use, aptly called microSD. They are a part of almost every portable device you can imagine, like cameras, mobile phones, tablets, and everything in between.




For devices not dealing with high-density data, a 32 GB SD card is preferable due to low cost and ideal capacity for everyday use. Those requiring a rapid exchange of data, such as high-resolution video recording or taking RAW images, a class 10 SD card offers blazing writing speed.




Few years down the lane, things weren’t always so universal. Many line ups preferred specific types of memory cards and attempted to make their ecosystem impenetrable by third party products. There can be no better example than Sony. Sony made a particular shape and size of flash memory card, called MemoryStick, for its camera line up, the Cyber-Shot. To further fortify the Sony ecosystem, its laptop line up, the VAIO, had a dedicated slot for MemoryStick while every other flash memory card needed a dongle so the system could read it.

Can you imagine a computer not capable of storing an ample amount of data? Well, there are a few flash memory card advantages and disadvantages. What good would it be if we were able to work on them but not save our data directly with ease? In fact, without this seemingly little piece of technology, you won’t be able to save anything on your phones, cameras, or other devices. What makes memory cards as reliable as they are, is their compact and non-movable design. 



Light-Weight Design & Non-Volatile Storage

Memory cards also decrease outlying threats to data such as the threat of losing power source. They can hold non-volatile memory which in return provides data stability on the card. Secondly, they are free of mechanical issues or damages, making them more promising. Not to mention, the small, light, and compact card is capable of holding an ample amount of storage capacity, with minimum energy required.



Highly Portable

The portability is one of the main factors, making memory cards so famous amongst modern tech devices. Modern device manufacturers are now focused on reducing the size of their technology without compromising on the features. Thankfully flashcards make that easy, as they are lightweight, require low power, and are silent. They also allow immediate access to data, what more could you ask for?




The preeminent feature of flash memory cards is the variety of sizes it offers. You can enjoy just as much data storage space as you need. The most commonly used size is 128GB as it has enough data to fulfill the majority of the storage needs of average users. 




Memory cards have now become an essential part of modern devices, including cameras, computers, or mobile phones. Why? Well, they are lightweight, easy to access and give you more storage at a cheaper cost making them highly cost-efficient.


You can even buy a flash memory card reader to read the memory card if the computer or laptop isn’t compatible with the one you have.



Great For Backups




One can’t undermine the importance of data backups. Not backing up data, can threaten your workflow if you need it later on. Imagine yourself working in a company, and you somehow fail to record the data by forgetting to back it up. The company won’t bat an eye before they fire you for risking the company’s good-will and messing with their record system. In any organization or institute, data backup is highly emphasized to avoid future problems. 




Although it’s equally important to get a high-quality memory card. Amazon’s memory cards have proven to work in an accessible and well-organized way. Including the Amazon Micro SD Card, which is great value for money.



The Only Drawback

SD Card



Since everything has its pros and cons, there is one major drawback to memory cards as well. The small and lightweight device is more likely to break easily or get misplaced. The smaller the card, the harder it is to find. This is a huge problem for people who store large amounts of their data in memory cards, as they’re crushable. Once you lose the data, there aren’t a lot of ways you could retrieve it. Moreover, due to their small size, people often find themselves misplacing flashcards quite often. 




Thankfully memory cards come in different sizes and shapes, suitable to the product supporting it. Diving deeper into the types of memory cards will help you better understand their capabilities and make a more informed decision in terms of which one would suit you best.



Secure Digital (SD)
