Interesting. Thanks. We haven't price shopped in many years. S3 prices have been very reasonable and the overall cost hasn't been high enough to warrant a change.
Thank you for the reply.
I think it is worth to investigate. As more people use it, the price will creep up rather fast.
Wasabi is a relatively new company, but Backblaze has been around quite a while (I think they started around 2005-ish). The disadvantage is that they have far less servers on non-US regions than Amazon does, but that's their secret of low price (in contrast, Google cloud is the most expensive becasue they pretty much have servers everywhere except China).
I believe Backblaze does have a datacenter in Europe if you need one in the location.
Unfortunately the biggest data transfer I did with Backblaze is mere 5tb-ish so I can't tell about their performance for bigger enterprises like you guys. I have no experience with Wasabi but their supposed advantage is that they use same system as Amazon does for better compatibility with S3-related services.
