It's a minor point....
Since when did the NVMe protocol dictate the use of SSDs, as opposed to custom-built flash chips, which already inherit the characteristics to deliver improved performance and lower latency, not only a minor point, but also totally irrelevent.
That said, I'm genuinely pleased that NetApp have finally found something to crow about, however short-lived.
Certainly more refreshing than listening to the Orange people drooling over Blade Servers.
