56TiB of gp2 SSD storage on Amazon would cost $6,500/mo (so $78,000/yr) - so if its a 1:1 setup they could afford to fail a couple more times. Now there's the question of would they need all that space in a cloud setup, but thats another story.
What concerns me, from the image, is that they seem to be using cheaper, consumer grade drives (Samsung 860 PROs I assume). This is asking for trouble - as they went through - 3 drives failed simultaneously. I've only ever dealt with Cloud infra, but even I know that drives that are bought together, tend to fail together. It's likely their new batch of drives will also fail simultaneously - backblaze has done a ton of research on drive longevity.
> drives that are bought together, tend to fail together
It's exactly the same as the lights in your house, all of these were made at the same batch with the same quality of material and used the same way, they tend to fall apart within a few days from each other.

Just seems penny-wise, pound-foolish to me.
