As a simple USB mass storage device, the SD700 is compatible with Windows, macOS, and Linux, but it also boasts a more exotic compatibility for mobile devices thanks to Adata's Android app. Unfortunately, testing that app would require a rather esoteric USB Micro-B to USB Type-C cable that we didn't have on hand.
Instead, we focused our attention on the software features that accompany the SD700's Windows experience. To take advantage of those, users must install Adata's archaically-named "HDDtoGO" software, which provides a unified interface for administration of any kind of external storage.
HDDtoGO comprises a hodgepodge of tools with varying degrees of usefulness. The Internet Options tab provides mechanisms to sync favorites, to store passwords, and amusingly, to browse the internet privately by hijacking temporary files that would otherwise be stored on a computer's internal storage. Other tabs allow users to sync files, backup and restore emails, and even turn an external into an authentication mechanism—Windows will lock and unlock as you insert and remove the device (as long HDDtoGO is still running, at least).
The only interface of particular interest to us is the Security Settings tab, which acts as a gateway to the SD700's AES encryption capabilities. Setting a password quickly and easily allowed us to secure selected files on the drive, which were then rendered inaccessible without the password.
Now that we're assured of the drive's security chops, let's get to testing. We may not have any sandblasting, waterboarding, or drop-testing benchmarks as part of our test suite, but we can still check how good the SD700 is at pushing files around. It's time for RoboBench.
