Initially I chose for the test winner on various sites of SanDisk (Extreme), since it clearly fulfills at least the criterion b. After unpacking but came the disappointment: too big / long-acting and cheap plastic that tends to scratch and the ratio to Euro GB is just ok. So back it.
Quite the opposite in this stick: which is not only fast (located in the tests only minimally behind the SanDisk Extreme) and offers a good / better GB to euro exchange rate but also looks damn good / wertig from. The mechanics for clean-and-Slide Out is very stable.
I currently use it although only one USB2.0 port (27MB write / read 34MB), but am looking forward when a new computer with USB3.0 full bandwidth (100MB write / 200MB read) exploits.
