Obviously that has to be reflected in the price of the product. Presumably even more so with storage.
Also there might be a use case, where cost is paramount and the drive would experience very limited writes.
I’ve got a personal anecdote that’s not entirely the same, but I’ve bought a bunch of flash chips from china to use with retro games. Those are often salvaged, but they are also cheap and available to buy. It doesn’t matter if the chips can’t take too many write cycles, if you only flash them a couple of times.
