I purchased one of the 'bue eye of suron' models.
Just wanted the thunderbolt interface to release a usb port.
Rattled like crazy, due to the disk not secured properly so I pulled it apart, stuck a bit of plastic in and that quietened it down a bit.
But the disk was still noisy, so I stuck a WD disk in.
Also the thunderbolt connection seemed poor cause it to disconnect.
Now its a backup disk using usb.
Bought a WD disk enclosure to replace it. Half the price, quiet, more capacity.
