I suppose it could be considered a trade-off? There’s the obvious advantages of longevity and possible size(?), it van still be viable in some niche uses where that matters. Github’s code vault from a while back could have benefited from that.

This is explicitly stated to be for cold storage though. It doesn’t have to be fast at all. And they’re supposedly aiming for 500mbps soon.

Did you read the article? 30mbps is faster than a lot of people’s internets. It’s not fast, but for a prototype, it’s not bad.
