Even a TLC (three level cell) claims 3,000 minimum write cycles. Using QLC SD cards, the write cycles will drop to 1,000 still well over your claimed 300 cycles.

These are values of the latest technologies; but Kobo uses SD cards - more than 10 years old technology, you can't get them in normal shops anymore.
Also: the standard SD delivery is that for the 2 per thousand GB there is a non-partitioned space for which the controller can swap defective areas - the rest is exFAT in huge blocks.
But that is not the case with the Kobo partitioning - the entire space is partitioned and sometimes in ext4 a very write-intensive file system because it is logging.
As soon as the first cell becomes defective, the card is defective.
And, of course, Rakuten wants to keep selling devices.
