See for example the storage systems from Vast or Pure. You can increase window size for compression and dedup far smaller blocks. Fast random IO also allows you to do that ”online” in the background. In the case of Vast, you also have multiple readers on the same SSD doing that compression and dedup.
So the feature isn’t that special. What you can do with it in practice changes drastically.
As you can with spinning disks. Nothing about flash makes this a special feature.

The difference is you can use inline compression and dedupe in a high performance environment. HDDs suck at random IO.
