No matter how resistant USB flash drives are compared with mechanical drives, they can still be damaged or corrupted by serious physical abuse. The circuitry of a flash drive can even be harmed by improper wiring of a USB port. And while USBs flash drives are appreciated for compact size, at the same time they can be easily left behind. This brings us to the biggest issue of the DT200. While most of us will love having 128GB of highly portable storage at hand, that's a heck of a lot of data waiting to get lost or stolen. Individuals and small-business users should question whether carrying around so much data is wise. In spite of the security issues, the DT200 is a very good drive that could be put to a wide range of uses. It's not the fastest or most individually styled but it's practical and functional. Having said that, I'd have liked some auto-backup software included in the bundle. The biggest drawback is price, which is shockingly expensive considering you can buy an external 500GB hard drive (2.5-inch) for under =A3100. Still, this is far pocket-friendlier. It is backed by a 5-year warranty and 24/7 tech support.
