USB-накопители информации корпоративного и индустриального класса и их отличия от потребительского сегмента
USB-флеш-накопители – уже привычное для нас устройство переноса и хранения информации. Несмотря на то, что большинство из нас переходит на облачные хранилища, флешек всё равно продаётся и покупается очень много. Они используются в решении бытовых задач, в работе офисов и индустриальной сфере. При этом специфические требования корпоративного и индустриального применения часто игнорируются. Выбор устройств, содержащих важную для пользователей и бизнеса информацию, необходимо осуществлять с полной ответственностью, поэтому в этой статье мы рассмотрим критерии надёжного хранения информации и разберём способы соответствия им.
