Indeed. They spent ~$1m of engineering talent and took on some significant technical debt in order to save recurring annual datacenter cost. I'd say if they reduced their datacenter annual cost by at least $5m it was money well spent. From the sound of it they actually saved a lot more than that. And by increasing their overall storage efficiency it's a feature that pays dividends even when they do ultimately add more storage in the future.
