If kobo use the same measurements ( & I cant be bothered to check) , an empty 8GB Forma will actually be 7.3 GB, and that's before firmware etc takes its chunk
1TB or ~930 GiB is quite a bit larger than 930 Mb.

NAND flash-based storage (flash drives, SSDs, etc) follows the same conventions as normal drives wherein 1GB = 1 billion bytes.

In terms of raw NAND capacity, a 1TB SSD likely has 1TiB or more. Given the way NAND flash works though (no direct overwrite), the discrepancy between decimal and binary is used as the minimum level for spare area/over provisioning.

8GB is around 7.45GiB. Around 1GB for firmware/OS related partition(s) sounds about right.
