best secure usb drives – DiskGO Secure GUARDIAN 2017

The DiskGO Secure GUARDIAN from EDGE Tech Corp. is quite comparable to the SanDisk Extreme Contour and the DataTraveler Vault Privacy Edition secure USB drives. Its disk-write speed is not as fast as the SanDisk, but it has a better warranty than the DataTraveler.

Attributes

The drive connects to Windows machines (and will soon operate on Macs) via USB 2.0 port. It also works with USB 3.0 computers. Packaged in anodized aluminum, the drive is designed to withstand vibration, water and sand. Disk-read speed is 27MB/s. Disk-write speed is 14MB/s. The drive is enhanced for ReadyBoost, a Windows Vista and 7 feature to allow the operating system to use up to 4GB of random access memory (RAM) for caching, to speed system performance.

When employers first became aware that data leaks were occurring via flash drives, the knee-jerk reaction was to ban their use and superglue the USB ports shut. The industry then began to market secure USB drives, some of which used passwords and encryption and some of which used biometric scanners to validate the fingerprints of approved users. EDGE Tech Corp. markets both technologies but the DiskGo Secure GUARDIAN???s approach to security is based on passwords and encryption.

The data are encrypted and secured behind a password. The drive keeps track of incorrect password attempts and it will erase itself after a certain number of sequential incorrect attempts. Because the encryption is hardware based, decryption keys never occupy RAM so keyloggers are completely stymied.

The AES 256-bit encryption conforms to the Advanced Encryption Standard defined by the National Institute of Standards and Technology. The likelihood of anyone being able to crack the encryption is inconceivable using 21st Century technology. If all of the computers in the world tried to apply brute force to decrypt the standard, it would take much longer than the billions of years that the earth has been in orbit around the sun. Confidence in the standard is so strong that, according to the Sarbanes-Oxley Act of 2002, if a company ever loses data encrypted by 256-bit AES, the government does not require the company to report the loss. Nobody is going to be able to crack such a strong level of encryption.

The drive works on Windows machines and a Macintosh version is imminent. EDGE Tech Corp. provides a limited lifetime warranty and technical support in the form of email and web forms.

Help & Support

The DiskGO Secure GUARDIAN is an excellent secure USB drive for Windows users and it will soon support Macintosh. The limited lifetime warranty from EDGE Tech Corp. is an uncommon benefit, matched only by one competitor: SanDisk. This secure USB drive is perfectly adequate if you are not buying for the government or for healthcare and financial institutions that are required to protect sensitive data with the use of drives that conform to the Federal Information Processing Standard (FIPS). If you really want FIPS validation, then look to IronKey and Kanguru. Otherwise, this EDGE Tech secure USB drive is a good insurance policy against personal or professional data leakage.
