I have a device like this and it supports heavy gpu inside my pc. Wery usefull and nicly built thing made from metal. But the consern is it has a magnet on botom side, so it sticks to metal surfece inside the case. Wery usefull again but my hard disk is under that metal surfice. So i wonder can it corupt data or damage hdd itself…?!
You would usually need a really strong electromagnet to actually kill a hard drive through magnetism alone.
And what about extended period of time? This thing is siting there and hard drive also for etrnity?
