Could be a stupid/bad question; is a three tier cache/mid/cold setup supported? Example would be: 1. Fast NVME drives —> (write-back)—> 2. Mid grade MLC SSD for primary working set —>(write-back)—> 3. Super-Cold EC Pool for cheapest-deepest-oldest data Theoretically, that middle tier of quality consumer or lower end enterprise SSDs would be cost effective to scale to a large, replicated size, while still maintaining fast performance. NVME could absorb heavy writes and fastest interaction, with the EC pool scaling behind it all.
