Maybe slight off topic, but does anyone know what the deal is with the NVMe K/V command set spec? There was a fair bit of noise made about it at the time, but I’ve not seen any drives that support it (despite a few enquiries)

If you don't command enough purchasing power to already be getting custom SKUs from your drive vendors, they don't have enough incentive to add those features to the models they offer you.
