These SSDs are perfect for storj usecase — the drawbacks don’t matter because storagenode writes very little and never rewrites any data. Even accounting for data amplification, 1TBw per months is nothing. The benefits — low cost, noise and power consumption.
I’m not sure why are they “bad” in your book.
I would argue booting from 2TB 980”Pro” is an obnoxious overkill, as is raid6 (!?) of just eight drives, let alone for a storage node (I would do raid0) — but it’s not my money so why not. If done carefully, manually overriding 512e bullshit when deploying the filesystem — it could work.
