Pretty sure it'd just be a thumbdrive. Are the Taalas chips particularly large in surface area?

800 mm2, about 90mm per side, if imagined as a square. Also, 250 W of power consumption.

The form factor should be anything but thumbdrive.

The only product they've announced at the moment [0] is a PCI-e card. It's more like a small power bank than a big thumb drive.

But sure, the next generation could be much smaller. It doesn't require battery cells, (much) heat management, or ruggedization, all of which put hard limits on how much you can miniaturise power banks.
