Review on High-Speed Data Transfer with SanDisk 128GB Ultra Flair USB 3.0 Flash Drive - SDCZ73-128G-G46 by Kristen Reid

The manufacturer claims very impressive characteristics, namely - 150 MB / s read speed, 50 MB / s write speed (as indicated in some sources) with a USB 3.0 connection, but will everything be so good in fact, how will it behave in real conditions. And so outwardly the carrier looks very stylish and neat, and not large, the steel case on the sides is enclosed in a tinted semi-transparent plastic, which has a bend that forms a comfortable handle. It's a pity there is no work indicator, the blue diode would look very much in line with such tinted plastic.
