I picked up this Lacie Little Big Disk, thunderbolt 1, Two 500gb SSDs RAIDed. To test it out I copied over 500gb, it got a bit warm and the fan turned on and made a little noise. I opened it up and cleaned & lubed the fan.
I was looking at the design and about the only place for the air to come out is around the ports and lock hole. Pretty heavy aluminium heat sink but it would help if there was better ventilation
I was thinking about the front but the appearance would bother me. However the drive has a stand so I’m thinking about cutting a hole on the bottom at the front. That’ll give it a little natural air flow and some place for the air to go if the fan cuts in.
