Depending on your needs, iPhone Data Eraser offers three different modes to permanently delete your iDevice content.
*High (3 passes): meets the DOD 5220 - 22 M standard
This option is by far the most secure data destruction option. It writes over the data 3 times by using the DOD 5220 - 22 M standard. Even a government’s facility with the state-of-art data recovery technology won’t be able to retrieve data afterwards. This mode takes longer but is the safest.
*Medium (2 passes): no one knows the data on your device is erased
It leaves no traceability of data erasure. This option writes two passes of random data followed by a single pass of known data over the entire iDevice. All existing and deleted data on your iPhone, iPad or iPod touch will be overwritten by random data.
*Low (1 pass): erases your iDevice quickly
Wipes off data on your iPhone, iPad or iPod touch with fastest speed. This option writes a single pass of zeros over the entire device, saving you time.
