Right, Clint.
That's exactly what the computer industry did with monitors. They shielded
them well enough to meet the standards.
The problem with solid state drives is different, but if they can solve the
radiation problem with monitors, they can do a comparable trick with drives.
By the way, I don't know whether Energy Star has to do with radiation. It
has to do with electricity consumption. Radiation standards are based on
TCO.
