  • More secure legally. You generally can’t be compelled to disclose a password that incriminates you (unless it’s already apparent that you’re guilty of wrong-doing) but a thing (physical key, fingerprint, etc) isn’t protected in the same way and can be demanded by the court.

    Whether biometric are secure or not is another question, they can be stolen like any other data or a motivated attacker could just take you or your fingers.






  • Interesting that the one has such large capacitors in it. I imagine that is as last-ditch effort to keep the board powered long enough to finish flushing all of its caches in the event of a power failure.

    That’s exactly the point of power loss protection (aka PLP.) As a side effect of not needing to wait for a flush after a write synchronous write workloads are dramatically faster on enterprise drives with PLP.

    Edit: To add a bit of detail - you don’t need to wait for a flush after a synchronous write with PLP because the drive firmware can lie and immediately return from a flush call because there’s enough backup power to complete that flush if the power were cut.
