Write burglaries

The stick is indeed designed for USB 3.0, use part of the stick does the interface only when the reading. This was aware before buying and I had a write rate of 8 MB / s or less may also make friends. But ... In the long breaks in larger or many small files the write rate to approximately 1 MB / s. This can not be due to the hard disk that has little to do, according to Resource Monitor something. Also, it may not be the problem of a computer, I've tested it on several. Always the same result.
Even worse it looks for parallel writes. Alone with two parallel orders the device falls back to the kilobyte level. Rarely bytes per second at 4 or more parallel writes.
Stops the reading rate, what it promises.
Conclusion, who wants almost only fast on his files or almost only reads files is well served by the device. Even during write operations interrupts the reading rate a little. individual documents or other a few smaller files can also be secure yet easily on the device. But if you want to accommodate, for example films or disk images or lots of small files in a certain time on the stick, should use other sticks.

If you want to make the drive to a keychain, you first need a relatively thin ring. The default is too large and allows almost no movement on a key ring, which may damage the storage medium result. Otherwise the stick makes a very robust impression!
