We have been playing around different types of USB flash drives to establish what works well with the xBible project
We had an old white Kingston 1Gb one bought 5 years ago, and as it was on our keys, the plastic casing started to get brittle and break off leaving its naked circuit board exposed, still working of course, but we copied all the data off it onto a new one and threw away. We would recommend Kingstons still today.
Some are so small now that they are too easily to lose. This HP 16Gb one in the middle was disappointing as its stopped working suddenly and its not even 1 year old.
The Sandisk blade is our favorite, it doesn’t have a cap (which get lost anyway) and its small but not too small and has minimal metal components. In theory this could be taken through an airport or border crossing and not set off the metal detector.
USB flash drives that come with some kind of special encryption already made up may not work well, as they are already divided into two drives, and this can’t easily be wiped off. In theory it might work, but this presents more complexity for the end user to use on his computer, especially if he doesn’t have an IT person to help him out.
For any Christian organization planning to implement xBibles into a country unfriendly to Christianity we would recommend buy a small number of one particular model just to make sure they work well before committing to buying a large quantity.
