Back in the 1970s, Signetics put out a joke data sheet for a
“Write-Only Memory” chip. Basically any data you sent to it would be
simply thrown away, and attempts to read from the chip would never
return anything. They were surprised to get a few serious queries from
prospective customers wanting to make use of this component.

 
i have some vague memory from the period using it (or something similar)
for optimal compression

I’m sure it works very well for deleted data.
