Smartphones increasingly come with more internal storage capacity, however either for performance or personal need, memory cards are still quite present in smartphones. Western Digital, which has merged with SanDisk since May last year, recently introduced two new memory card lines that withstand extreme temperatures, whether cold or hot. The news is aimed at users of commercial drones, security cameras or cars for backup.
In the SanDisk Industrial family, there will be two SD cards and one microSD. The former will have storage ranging from 8 GB to 64 GB, but the difference lies in the temperature range supported. While the most basic version can operate between -25 ° C and 85 ° C, the XL model will withstand a cold of -40 ° C or even 90 ° C heat.
Already the smaller device will work in the same temperatures of the most basic SD version. However, it may have a storage of 128 GB of data.
The second line is SanDisk Automotive, created especially for use on cars, drones and other vehicles. It will only have an SD model, with capacity between 8 GB and 64 GB, and will operate in extreme temperatures between -40 ° C and 90 ° C.
All memory cards are expected to support tools such as Power Protection – which prevents data from being corrupted in case of an error in the middle of the write – and Host Lock – which allows users to create a password to access the files.
In addition, they must have a minimum writing speed of 10 MB/s and 80 MB/s for reading. As the task of transferring files between the computer and the memory card is so easy, the speed at which it takes place could not be lost. In this card, SanDisk was able to put a file transfer speed of 80 MB per second, which puts it in category 10 in terms of speed. Although in the specifications the speed is only 80 MB / s, after some tests the card showed speeds above 95 MB per second.
Western Digital has not released pricing or launch forecasts for the new storage devices. However, they are already undergoing testing and experiments by partner companies.
