>I secure wiped my SSD from BIOS. it took like 3 seconds. how could it be this fast, isn't it supposed to take at least several minutes? it's a Crucial 1GB.
do you mean 1TB?
it's done "in hardware", but you shouldn't trust that shit.
an analogy: in some cases software sends commands to simply "delete" encryption keys from SSDs, but there is research that shows that "hardware encrypted" data can be recovered, and keys are reused or insecure keys are used once and once again.
just run dban or dd if=/dev/urandom of=/dev/your-ssd
