In addition to a server, I use internal sata drives externally as offline backups. I use a front sata panel to attach the drives, as can be seen here: Akasa Thermal Solution
However, placing them on my desk surface is somewhat precarious, as the surface is hard and provides no ESD protection.
To the question: I'm looking for some sort of mat or pad, aproximately 12"x12" (give or take) that will absorb impact and protect against static electricity. I would think these would be fairly common, but apparently not.
