Memory card has many advantages. They are small, mobile and supported by a giant set of equipment, making them very convenient. But it is not trustworthy as a reliable drive, protected – at least no backup plan. Makeuseof.com information portal speakWhy.
Physical fragility
Advertising memory cards are universal and mobile data drives; Some manufacturers even think their cards are waterproof, shockproof and X -ray radiation. And yes, these are useful if you suddenly drop the card into the puddle, but in everyday life, they do not fix an important drawback. Any memory card is a small, thin plastic piece. It may be broken sometimes extracted from the device, slip out of your finger and break on the hard floor, or get lost.
Even if you are careful, small contacts on the back panel of the card may be scratched or wear out over time, which will lead to reading errors. They also suddenly bent if they are stored not in a special protection case. And although some cards can actually exist a trip to the washing machine, others immediately fail.
Compatibility and fake issues
The memory card market is a bit similar to the wild west. When you lack knowledge, you may think that buying from a big brand is quality assurance, but no. Fake memory cards everywhere, especially if you put them in online stores. They often receive huge brands promising, but in reality, of course, there is much less empty space. Users are worthy of exceeding the limit, the way the card will start rewriting the existing data – you may not need to explain that this is bad.
But even if the card is not fake, you can always encounter compatible problems. Some old cameras and other devices cannot deal with new, spacious SDXC cards and this leads to recording or reading errors. Others – Card format in a way that is only partially compatible with another electronic device, so the motion of the card between different devices is a risk. Sometimes, it is often difficult to understand exactly what the problem is: in the map, read the device, cable or the camera itself.
Quiet incident
Hard disks have some symptoms that you may notice serious problems coming. Strange noises, reduced performance, an ominous click sound. But the memory card, unlike other drives, is often broken in complete silence. They only sit inside the device and do not have any signs of trouble … while the files on the drive slowly damaged. Only a few data may be affected, but you will not find this, until you connect the card to the PC.
