Amazon Echo Dot does not wipe personal content after factory reset
>Since the storage media in these IoT devices would not last long if true deletions were being performed constantly, “deleted” data is often simply invalidated and moved to an unused page in the block (in a process called “wear leveling”). These invalidated pages, which still contain the data, remain present until a block fills up with them and a true deletion is initiated.>Accessing flash memory that has been factory reset in this way does require some amount of technical skill and specialized equipment, but nothing that is a real barrier to the average enthusiast working at home.By that logic my iPhone 11, my Android phone, my Mac or my Windows PC doesn't wipe personal content either after factory resetFeels like a bit clickbait-ishBut at least Macs have a built-in 7-pass erase option to comply with DOD standards https://techpatio.com/wp-content/uploads/2012/09/disk-utilit...
