Those aren't hard drives, they're solid state drives in the SATA form factor which was originally designed for hard drives. SSDs are much more compact than HDDs, so the components are usually all bunched up at one side near the connectors and the rest is just air, thus punching a hole in them at random probably won't achieve anything. Punching a hole through the PCB might not destroy the data either depending on where exactly you hit it but it would at least make it difficult to recover.
