"Endurance is also cut in half from the 100E series, from 219,000 to 109,500 TBW — though the drive still manages to match the 1TB version of the 100E in endurance."

That's technically misleading, kinda like a red apples to green apples comparison. The actual chips have identical endurance per TB. Doubling the size of an SSD doubles the amount of space to write to doubles the endurance.

This is a common practice for all SSDs I've seen in the consumer market

How is it getting to that TBW, by using SLC NAND?
All their spec sheet says is 3D NAND, which doesn't tell us much. SLC would definitely give a cycle of 100,000, but maybe the are just way over provisioning with TLC (which would seem unlikely). I couldn't find any concrete information beyond their sites spec sheet.

Something is very odd here. The current TBW for regular NVME drives is between 600 to 1200 times the size. This is 100,000 times the size. And if true is a quantum leap forward.

Apparently it uses pSLC, quoted within the article is 3000p/e cycles, 100,000p/e cycles in SLC mode.

From Cactus
Industrial pSLC products are based on pSLC NAND, which stands for Pseudo Single Level Cell NAND and is the same MLC NAND as used in Industrial MLC. The difference is the MLC NAND is set in a mode which only the top and bottom states are used, thereby cutting the capacity in half but increase the endurance by 6 times the MLC”

That is due to most consumer drives using TLC or QLC NAND which has far less durability than SLC or MLC. The trade off is SLC and MLC cost more per GB than TLC or QLC does.
