That kind of dynamic SLC is fun if you have cash to spare or you want to play around with a brand new drive.

Otherwise what I care about is the minimum SLC size. Or, if it's significantly different, the SLC size when the drive is 80-90% full.

Operating word was "enterprise" :~)

Edit: I think I get your query about "minimum SLC size": I imagine that the cache isn't scaling 1/3 of capacity across all SKUs 1-4TB.

Even in enterprise, buying drives three or four times as big to ensure consistent maximum performance is something you'll only do some of the time.

By minimum, I'm talking about how a dynamic SLC cache is by definition using spare space in the drive. If all those cells are filled up with TLC data, they can't be used as SLC cache. But one drive might guarantee 5GB of SLC cache even when it's near-full, and another drive might guarantee 100GB, and those drives will have very different performance characteristics.
