I imagine at times like this a small USB-3.2 device which is a RAID-6 array of 20 or 30 microSD cards, probably a small FPGA to provide the 30 port SDIO device that can do 100MB/s per channel, a two gigabyte static ram with battery backup (coin cell) for holding open stripe state, and a SCSI or SAS export point for reporting out as a drive. Device is probably the size of a deck of cards, maybe smaller, consume or feed data at a GB/s all day.

That would be pretty freaking amazing.
