Do you need to secure erase your SSD?
When erasing data from an SSD, information is not terminally deleted but simply overwritten. This means that space is created to store new information, but the deleted data is still present on the SSD and can be easily recovered. This presents a very concerning security problem for industries where confidentiality is critical.
With older spinning hard drives, applying a strong magnet — also called degaussing — could effectively delete data. However, this doesn’t work for SSDs, where traditional solutions for secure date erasure are physically destroying SSDs, encrypting data, or relying on a third-party software or company to wipe the devices.
However, these solutions are impractical, expensive, and require the data owner to trust a third-party service provider with the sensitive task of handling and destroying private, confidential or classified information.
The X-PHY® has a built-in secure erase function that ensures that data is completely removed and cannot be recovered, protecting companies against the danger of data leakage and theft. This function, which is unique to Flexxon’s products, is ideally suited to safety-critical environments — such as military applications — where a quick and effective data wipe might become necessary.
The data purge function is selectable on the drive’s set up and can be selected or unselected at anytime by the user on the control software. The user can opt for a rapid purge that includes encryption key purge or data purge. If the key is erased, data can no longer be accessed but remains on the drive. If the data is physically purged, it cannot be retrieved ever again.
These functions can be found in the X-PHY®’s control software but require authorisation via password. If both “physical” and “wipe data” functions are enabled and the device experiences disconnection, the data encryption/decryption key will be erased in nanoseconds and when powering on again, all data will be purged. In this way, the SSDs can be securely erased with a click, meaning there is no need to rely on external services.
