To the contrary, my company's experience with SSDs - including data logger
installations in high RF field density environments such as EMC chambers and
collision avoidance system test rigs - is that they are more reliable overall,
and much less susceptible to RFI than electro-mechanical disk drives. They are
increasingly common in instrumentation systems, including Agilent RF lab and
field equipment.
Consider that the typical HDD control board - essentially a servo controller
and a signal processor - is mounted outside the enclosure, and that an SSD is
basically a "state machine", and the difference in susceptibility makes sense.
They also emit less RF for exactly the same reason - most everything is
enclosed.

them! From what I can gather, they are far less reliable than hard disk drives.
Personally, I would not use them.
