Hi Giktimes! As you know, conventional memory cards are designed to work in fairly mild conditions. They will not tolerate extremely low or high temperatures, there is no protection from x-rays, and if dropped from a great height, the flash drive will most likely become unusable. Well, then the use of memory cards is not limited to the domestic sphere, data carriers are needed in steel production shops, on intercontinental container ships. In addition, it is necessary to establish video surveillance systems in places where it is very dangerous for a person to be: at power plants, in high-temperature furnaces and at warehouses of mining enterprises in Eastern Siberia. For such tasks, you just need a series of durable, reliable and hardy cards. .
Cards Industrial Temperature microSD UHS-I capable of operating in the temperature range from -45 to +85 degrees Celsius. That is, in fact, everywhere: in Antarctica, in the Sahara. Since they are called industrial, they are mainly used for serious purposes: in modern military equipment, energy sectors, laboratories, construction sites, and the space industry. Here, the security of the card and its ability to work in harsh conditions come to the fore.
If the equipment is left at a low air temperature for a long time, the card will not suffer either. So Kingston Industrial Temperature flash drives are also suitable for field work, when equipment has been standing in the cold for weeks.
At a construction site, it is quite possible to use a quadrocopter to fly around the territory - for example, when building a skyscraper. Such a video is easy to shoot, and it will not be superfluous at a presentation to investors or construction customers. Renting a helicopter will definitely be much more expensive than a quadcopter with a GoPro hanging on it. However, aircraft sometimes crash and it is important to preserve the footage. Ordinary memory cards do not have protection against drops and vibrations, while flash drives of the Industrial Temperature series guarantee microSD performance after serious shocks.
But what if we abstract from industrial tasks and imagine how Industrial Temperature series flash drives can serve the benefit of science? After all, video filming is often used to record the progress of the experiment. You can take something simple - slow motion freezing of a plant with liquid nitrogen, or you can reproduce the world-famous "SchrΓΆdinger's cat" experiment.
We believe that the essence of the experiment, which has never been carried out for real, all of you know very well. A certain cat is locked in a steel chamber along with a device that is completely immune to the cat's influence. Inside the Geiger counter is a tiny amount of radioactive material, so tiny that in an hour only one atom can decay, but with the same probability it may not decay. If it does, the reading tube discharges and a relay is triggered, triggering a hammer that shatters the hydrocyanic acid vial. Outside, it is completely impossible to determine whether the cat is alive or dead. But you can install an autonomous video surveillance system in a steel chamber, which in the end will help determine whether the cat is still alive. And if not, was it the result of the experiment, or did he simply not stand the boredom and kill himself on his own?
But protection against falls and high / low temperatures Kingston was not limited. Cards are tested with sudden temperature changes and changes in humidity to make sure that the flash drive works in any conditions. The check lasts several hundred hours, during which the card is heated, cooled, heated, dried, the humidity parameters are twisted to a minimum and maximum, passed through X-rays, and then all this is repeated in different sequences more than once. The result is a terminator card that can survive almost any external impact (except, of course, a sledgehammer). The manufacturer has provided for the frequent removal of the memory card - sometimes the flash drive can be accidentally broken in this way, or the plastic will be damaged from frequent extractions. Cards are designed for at least ten thousand insert-remove cycles. This will be enough for many years - the card will become obsolete faster than it will fail. The official warranty, by the way, is five years.
The card has a number of certificates confirming its resistance to external influences. So, Kingston Industrial Temperature microSD is rated IPX7 - this means that the flash drive can withstand half an hour being under water at a depth of one meter. But these are trifles compared to the military testing methodology according to the MIL-STD-883H standard. The method, designated 2002.5, assumes short-term exposure to the force map from 500G (duration 1 m/s) to 30G (within 000 m/s). Fragile-looking flash drive passed without exaggeration a serious test. Radiation protection complies with ISO 0,12-7816 certification. The card withstands 1 Gy of X-ray radiation both from the front and from the back. This dose corresponds to 0,1 rads or 10 mSv. For example, with film fluorography, you get a dose of about 100 mSv, and from X-rays even less - 0,5 mSv. It is considered that 0,3 Gy is the allowable short-term exposure in emergency situations.
Industrial Temperature cards are available in sizes from 8 to 64 gigabytes. Specifications vary by volume. All flash drives have a read speed of 90 MB / s, but the 8 GB version has a write speed of 20 MB / s, while the 16, 32 and 64 GB models have 45 MB / s. Speed ββclass - UHS-I Speed ββClass U1. Such high-speed performance removes any restrictions in shooting: slow-motion video in Full HD at 120 frames per second, shooting in 4K resolution, fast burst of photos - the card easily copes with any tasks.
Testing in Crystal Disk Mark using a Kingston FCR-HS4 USB3.0 card reader showed a slightly slower speed than advertised. The 16 GB card showed almost 84 megabytes per second in read mode and almost 47 MB ββ/ s in write mode.
Kingston has made the toughest memory card out there, and there are many areas where the ability to record at extremely low or high temperatures really comes in handy. Drop resistance is also not for show. Filming on GoPro and similar extreme cameras are gaining popularity, drones are increasingly being used in amateur and professional videos. Broken devices are not as important as the information directly recorded on the card. Kingston Industrial Temperature flash drives will protect your data from any accidents.
