SanDisk Cruzer Pen drive is one among worst pen drive I seen ever. I dont why SanDisk still manufacturing these kind of pen drivers. Because rest of all other pen driver from SanDisk are having amazing quality but this alone dont have sufficient quality.
The major reason is less price. You can buy this product any where in market at low price compare to other SanDisk Pen drivers because its build quality was very bad. Its USB 2.0 comes with very slim in design you cant get such slim pen drivers at this price. The main disadvantage in this pen drive is very slow transfer speed.the maximum transfer speed is about 4 MBps only.But now a days latest sandisk pen drivers comes with grate transfer speed like 300Mbps. when we are try to transfer about 10GB files it took lot of time as well as huge amount of heat getting produced even you cant able to touch device at that time due to over heat.
If you want buy Pen Drive with good transfer speed then dont go for this SanDisk Cruzer. Its better choice go for some other SanDisk Pen driver like SanDisk Ultra Fit USB 3.0 Pen drivers.
