AAAAB, personally I only had 2 KO criteria:
* Water and breaking strength
* And veeeery many GBs
On this I save scrambled format the most important documents, photos, music, programs, etc.. You could even a small piece of folded paper together tuck, eg for its own address, bill ... water resistance I tested myself with full satisfaction. Stick to, let into the water> 1T are, dry, and everything works perfectly! As is common in the mass media, 256 GB are reported as raw size using 1000 bytes per KB basis, not 1024. Accordingly, one sees on the PC "only" ~ 238 GB.
Breaking strength I have not been thoroughly tested, because I did not want to scratch, but dropped on a hard surface or on the roof garden soil makes the stick from nothing. On YT one finds a beautiful extreme hardness test video of gadgetgearnl (64gb Version): Barbecue, hammering, freeze, thaw with fire throwers, etc. no problem, and there is no distortion to see. For sister models it there like extreme tests.
CONCLUSION:
Who wants to have high speeds for office use, may be disappointed. This is primarily suitable for moderate to extreme conditions.
