ITReviewed posted a review on the Kingston DataTraveler 200 (128GB). Kingston's DataTraveler 200 (DT200) is actually the world's first 128GB USB flash drive - that's enough storage for around 182 music CDs (remember those?) or up to 27 DVD movies. Do not worry if you don't need the large capacity (or price) as the wholly-black DT200 128GB (from £293/$376) also comes in a blue-and-black 32GB model (from £58.58/$80.99) and yellow-and-black 64GB model (from £103/$143) capacities. The price premium is definitely on the 128GB unit.

Unfortunately there is no write-protect mechanism. The downside is that the cap is a little loose and makes a rattling noise when shaken, plus it doesn't actually cover the end of the USB port. The relatively thin plastic case feels vulnerable too, and I'm not sure how much abuse the drive could withstand on a daily basis. It certainly feels like it would split right open if stood upon, which isn't great news for frequent travellers.

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, especially considering there is no backup software provided.

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 £100. Still, this is far pocket-friendlier and is backed by a 5-year warranty and 24/7 tech support.
