Write Protection prevents drives from unauthorized data write via a hardware switch/pin or software command. With the write protection feature, users are guaranteed that their data cannot be over-written on the Flash device by triggering the write-protect function.
Why Write Protection?
Write Protection helps prevent data from being accidentally overwritten or erased. It’s a locking mechanism which prevents modification or deletion of data on a storage device. Generally, once your SSD or other storage devices are write-protected, you are not allowed to delete or edit data or files.
How Does It Work?
Write Protection can be enforced using either software or hardware. It’s usually a hardware switch in the case of diskettes to toggle write-protection of the entire drive. In addition to the hardware switch, Write Protection can also be triggered through firmware commands which can be customized depending on customers' requirements.
