5400 to recycle an old tower at low prices, a great product basic but works very well the diode is placed at the back and not blinking before you aggressively all being well visible (japprécie) the cover is good if your disk vibrates (or just to wedge it in a bag) the aluminum dissipates Screwdriver is the gadget (lol) I probably would resume (usb 2 usb connectors are really rotten and still break too easily for the moment on too much housing, damage) fast delivery and carefree
