That is something useful! The case is delivered with its power adapter and a USB 3.0 cable to good; all is sober and discreet, all black, with a circular LED facade reflecting the HDD system activity and a blue band that gives one side "high tech" to the device. the input component is obviously to let mobile hard disk 3.5 inches, and has an opening for a 2.5-inch pass directly without opening the door. the connection is fast and stable, the disc appears obviously in the same way as if he were in an external housing. The flows are consistent and regular. attention to the 3.5-inch disk heaters, used to being mechanically ventilated; time will tell if the lack of fan is harmful because it is true that if it is not broken, yet they are in the open air ... In any case, an inexpensive product that will give new life to my hard drive, not that old, lavishly increase my capacity external storage, and above all avoid me ruining my usb boxes of all kinds.
