Is Samsung's hardware encryption actually good or will it bottleneck my computer?
It's already encrypted when you start using it.

Try it and find out. That said, having done zero research on it, I would fully expect the likes of Samsung to hold encryption keys.

Just layer your encryption of choice overtop, AES is fast as fuck on CPUs.
In linux sata secure erase in gnome-disks drops your drive's encryption keys, effectively destroying all the data in less than second as well.
