Backblaze's design, by their own admission, is good if you have low IO usage. Internet Archive has a much different usage set, where the instantaneous IO needs are higher, and thus, the backblaze design would be way too high latency for them. Things like caching and ECC are much more useful when you have the hot spots that Internet Archive tends to have.

I get that. Time to first byte isn't critical with the internet archive, and they could use a robust caching later (varnish?) in from of their s3-similar storage system.

Cloudflare would argue that time to first byte isn't critical, period
