I was looking for DAS options but there are not many on the second hand market where I live.

I saw on AliExp. that there are these 12 bay 3.5-inch hard drive cage. It says that the drive bays were taken off of old servers. The back of these tiny depth disk arrays is a board with 2 SaS ports.

For me, the DAS is more educational. I wanna play with it at home. And it would be favorable because I don't have a rack.

Has anyone tried these?
