Disadvantages: Actually not 16 but 14.6GB

Comment: Brilliant such a blue light bulb)

Advantages: Works

Disadvantages: USB2.0 speed and not 3

Comment: no indication
cap quickly lost

Advantages: good speed characteristics
classic design
optimal price for its class

Disadvantages: Not detected yet

Comment: Choose between this model, JF 780 and Sandisk Extreme. The latter is all good, but the unprotected connector is annoying.
I did not take the JF 780 due to the lack of need for extreme speeds. In addition, JF 780 does not provide good speed for small blocks for its money, unlike Sandisk Extreme.
In the JF 750, on the contrary, everything is balanced perfectly - the price fully corresponds to the speed. Heard about the unreliability of Transcend as a manufacturer of flash drives, but the JF 700 is still alive, although it is being exploited mercilessly.
Judge for yourself on benchmarks.
Motherboard: Gigabyte GA-Z87-HD3, Z87.
