SSD – New Market Invasion!


Early computers took up entire rooms in large, specialized buildings, with limited amounts of memory capacity and low problem solving abilities. Today we carry in our pockets more efficient and complex devices than those primitive ones, with greater capacity for computational functions than the monstrous machines of the past. Likewise computers have evolved, both the internal and external memories have increased storage capacity and decreased in size.

The first memory settings were created in the 1990s, they worked through parallel communication, and are no longer used today because of the innovations that have occurred in the last 25 years and that still occur every day. Memory cards as we know today are derived from the ones created by Toshiba in 1980, this technology is called Flash and allows files to be stored on such cards and remain in this state for a long time, without the need of any type of electricity to function. In fact, today’s cards can store data for up to 10 years without any corruption of the files.

This semi-permanent storage capacity is one of the strengths of the memory card; another is the ability to be reused: once the data stored on the memory card is transferred to the computer you can delete it and use the card again, as if it were new. There are many stories that describe the durability of these cards, cameras that were dropped and broken beyond repair still preserve photos intact on those cards; there are stories of memory cards that have been forgotten in pockets of pants, washed and found again after many days without any damage to the archives or the card itself.



Over the years various types of cards were created, and three stood out some time ago for being the most used in different types of cameras Compact Flash, SmartMedia and Sony’s Memory Stick – and these three types have become about twelve these days, and they are not, most of the times, compatible with each other. However, the one that is most commonly used, is the microSD card.

The SD (Secure Digital) launched in 1999, in a partnership between Panasonic, Toshiba and SanDisk, with the ability to store encrypted data, and is used in smartphones, digital cameras and DSLR cameras, MP3 players and other gadgets, allowing it to be so popular. Its initial storage capacity was 512MB, while the latest cards (SDHC – Secure Digital High Capacity) store hundreds of gigabytes of information and data.


There are many memory card brands, with varying prices, varied storage speeds, varied storage capacity, all according to the uses foreseen by the consumer. AliExpress provides thousands of options to buyers, from simple microSD cards for personal use, with only a few gigs of storage, to the SD and SSD high performance cards, with increased storage speed and hundreds of gigs of storage.

The cheapest ones cost only a few cents, but as we have discussed about the cost-effective patterns, they tend not to be as effective as the more expensive ones. When you filter the search results to only display ads over US $ 5 it is possible to find better quality cards with more storage capacity, more aligned with the reality of regular users of memory cards. At the other end of the spectrum, there are lots and lots of memory cards being sold at wholesale for thousands of dollars; besides these ads, for US $ 99, a top notch memory card microSD can be bought, with an adapter for SD, storage speed of 48MB/s and storage capacity of 128GB.
