Let's see...we magnetize a small chunk of material, then pass the
same "chunk" past a 'reading head', which one might visualize as a
small coil of wire...and as it passes past the 'magnet', a small
electric charge is generated in the coil of wire.....which is read as
a 1 or a 0 (it is, or it isn't)......
We reverse that procedure to 'write' to the assembly of 'chunks', ie,
hard drive or flash memory.........
So am EMF will wipe it all askew.....IMHO

EMPs affect more than just magnetic media. If the EMP puts a high
enough electric field across the flash cells, it can erase/write the SSD too.
Magnets won't affect SSDs. Flash memory is electric field based.
