Security & Privacy

One other important factor when transferring data from your PC to your USB is how much security can you provide to all your private files that now exist on the USB drive. The Extreme Pro USB 3.1 has completely taken care of this aspect in securing your data and privacy to a great extent. The SanDisk USB 3.1 comes equipped with a SecureAccess software that enables you to protect all your files with a password with 128-bit file encryption.

The software is extremely easy to use as all you need is to create a folder on your flash drive and protect it with a password. When you copy files in this folder, all the files get automatically encrypted with a 128-bit file encryption. So you never need to worry if you misplace it somewhere or when your flash drive gets stolen, as no one could access your files unless they have the password to open the folder.

Also, the Extreme Pro USB 3.1 also comes with another great utility, the RescuePro Deluxe software that lets you recover any files that you could have accidentally deleted from your flash drive. But you need to have this software downloaded into the USB drive as it doesn’t come pre-installed on the flash drive.
