Why not both? I'm working for a nonprofit organization that refurbishes computers and servers for schools and people without the funds to aquire a computer, and if I can be ready to provide, the organization I work for, devices or a fully working system to securely wipe, currently non-wipable, peripherals like NVMe drives and AIC drives, that would be the best. That way we would be ready and able to wipe, never obtained yet, drives that uses PCIe interface and maybe another type of interface not yet developped. Recently, we bought a device that allows us to wipe NVMe M.2s and U.2s. But it did cost us 11 250 $CAD and since we have troubles aquirering new employes due to budget limitations and also since we don't really earn much money at all, it would be great for us to be able to build a system that would wipe almost any drives without costing an arm and a leg.
E1.S, E3.S, E3.L would be the types of drives that would be useful for us. We haven't received any yet but since we get donations of more and more recent computers and servers means, one day, we will surely receive at least one of those types of drives and, to ensure data privacy of donators, we have to be ready to wipe every private data we receive.
Sorry for the long text, but I felt like it was important to say how it could be used. As for me, this is my kind of "scenario".
