Very noble and beautiful USB flash drive

+ Positive:
The outer shell is made of cast iron, very rugged, quite massive, not a two-parter. With this stick you need have no fear that the breaking times. Visually, it looks very classy, ​​I guess brushed stainless steel. The USB3.0 specification is recognized by the subtly shimmering blue plastic holder for the USB connector. The stick is a little thicker than a conventional key, falls on a key chain but not on. In hole itself the case is not closed, if this is an advantage or disadvantage I can not judge. Just easily water and moisture penetration, as / well can escape them again.
The customer service is exemplary. Call immediately accessible and competent. My stick in any case I phone due to the rather below average read / write speeds (see below: Negative) objected. A new with a Qualtitätskontrolle is on its way to me. If the velocities be as expected good, the evaluation will be adjusted.

- Negative:
For the price, the read / write speed is really not to USB3.0 standard. I tested the drive on a USB3.0 port with korrektbem drivers and internal SSD (a 4GB file, not small and many files). Here are the results of my 16GB sticks:

Reading:
USB3.0 meZmory (16GB): 99.0 MB / s
USB2.0 China Key: 55.2 MB / s
USB3.0 Sandisk Ultra: 149.0 MB / s
USB2.0 WD HDD: 36.1 MB / s
USB3.0 WD HDD: 103.0 MB / s

writing:
USB3.0 meZmory (16GB): 13.4 MB / s
USB2.0 China Key: 7.3 MB / s
USB3.0 Sandisk Ultra: 191.0 MB / s
USB2.0 WD HDD: 43.4 MB / s
USB3.0 WD HDD: 86.5 MB / s

The read speed is more than okay.

Update:
After telephone contact was explained to me competent, why it is that the write speed is quite slow with USB3.0. This is the chip that the "dot" because of the small construction not ge can be, as this would be bigger again.

Who is not dependent on the writing speed, is operated with this USB stick on a key ring very well. However, I have added myself a classic stick of SanDisk (Extreme).
