The strongest point of the Corsair FlashVoyager USB lineup is definitely their ruggedness. I had a really great time during this review, while trying to break the stick. As long as you do not expose the stick to really high temperatures and do not put it into the microwave, everything else you can do to it during daily life, will not break it.
Not only can the stick take a lot of beating it also offers solid read and write performance. There is no driver installation required when using the stick in Windows 2000 and up.
Unfortunately Corsair uses a cap design, which means the cap protecting the connector can easily get misplaced. Adding a spare cap into the package would be nice of Corsair. During my testing I never had a feeling that the cap could fall off the stick.
The price of the Corsair FlashVoyager is about 20% up compared to similar sized USB 2.0 sticks, but if you plan on using the stick regularly this is a good investment. You also get faster transfer speeds. In my opinion the sweet spot regarding price/size is the 1 GB stick which can be found online for $65. 512 MB might be too small if you want to transport a CD image.
