Both drives were formatted with the NTFS file system. In my real-world 20GB file and folder test, the 4000 G2 was quite slow during the small text file portions, but when it hit slightly larger files it took off and still bested the Aegis Secure Key 3.0 170MB/s to 108MB/s reading, and 33.8MB/s to 32.8MB/s writing. I’m guessing oddities or a trade-off in the encryption algorithm. I used the 32GB units for my reviews.īut CrystalDiskMark also rated the 4000 G2 as being ten times slower writing 4K files than the Aegis Secure Key 3.0 at a miniscule 3MB/s. The latter is a more common result, so props to the 4000 G2. CrystalDiskMark’s 4MB and my own 20GB large file copy tests saw upwards of 230MB/s with the 4000 G2 compared to the Aegis’s 122MB/s. The Aegis Secure Key 3.0 is a lot faster than its USB 2.0 ancestor, but the 4000 G2 proved faster still. However, I think it should have a secure virtual keyboard for entering data when you suspect or are worried that your keystrokes are being logged. The software is simple, elegant and seems secure. The drive is divvied up into a 16MB portion that emulates a CD containing the installer for Windows, OS X, and Linux, and the data partition, which becomes available after you create and enter a password. If it weren’t for the label and a slightly heftier feel, you couldn’t tell the Data Traveler 4000 G2 from a non-secure USB thumb drive. The key isn’t this long, that’s the cap attached on the back. Kingston’s Data Traveler 4000 G2 needs to be unlocked from the computer it’s connected to. Few people need to access their sensitive data on anything other than a computer, but if you do, a secure flash drive with a keypad is the way to go. That is, once unlocked, you can use it with anything that recognizes USB mass storage-car stereos, media players, and Smart TVs, for example, as well as PCs and tablets.
