I'm curious, given the fact that they have physical access to the device, would it be possible to clone the hard drive as it is on multiple devices, and then brute force the passcode in parallel?

The flash is encrypted using a unique key that is burnt into the CPU at time of manufacture. So it is not possible to read back the contents on another phone even if you have the passcode.

  What's stopping someone from placing the silicon under ab electron microscope and reading the data visually? I mean, the circuit that encrypts data has to have some way to load the key (the circuit might not be in the CPU, but it exists somewhere).

    There is not an infinite amount of budget to solve any particular case

    Somewhat related, this sort of concern was mentioned in this talk about security on the XBOX One, https://youtu.be/U7VwtOrwceo?t=668 https://youtu.be/U7VwtOrwceo?t=668 Essentially they set an max budget for cost-effective attacks on the hardware, "modding the console needs to be more expensive than 10 games" (about $600), and ignored attacks that cost more than that to for an end user to execute.

  The article indicates they _were_ hacking a clone (mirror) of the data... which is curious, since Apple does claim there is a hardware key to prevent exactly that. Presumably someone is doing a little lying-by-omission - Probably there is a way to clone the device key with sufficient access/tooling, but that is pure conjecture.
