This case is very light. There are no instructions at the same time, there is no need. I put a 240GB SSD (a sandisk), I clipped the disc and then closed the case. I connected the USB cable to the box and to my computer. I did not need the little foam to wedge my record, he returned without problems and will not move.
A blue LED flashes to indicate that the drive is plugged. Perfect. Then I went into the disk manager, I assigned a letter to my hard drive formatted and have no problem.
I did a test, I copied almost 9GB top in just about 5 minutes. The transfer speed ranges from 50 to 10MB / s which is after all very well, the average is around 20MB / s. The case therefore holds the road well.
In conclusion, this case is effective, it fulfills its mission at an unbeatable price and offers me the power of the external drive ssd in order to quickly read my videos and other large bulky files.
