There are a few things you need to keep in mind with Wasabi. Depending on your payment method, there is a 90-day or 30-day minimum storage duration policy. This means that if you upload an object, then 30 days later, delete the object. You will be billed as if the object is active(even though it is truly deleted) for another 60 days. You may use more than expected if you have high amounts of short-duration churn of your data. If you have long-duration storage needs, this is great.
The other thing is that while egress is free, there is a fair egress policy. This means you should not egress more than you store on Wasabi monthly.
For example, if you want to host web assets, Wasabi could be a good fit if you use a CDN to frontend all the egress. However, if you do not use a CDN, you will use up your egress ratio quickly. While there are no extra charges, you will get notifications from the support team to figure out the issue.
Other than that, if you are looking for object storage and neither of the above bothers you, Wasabi is a great high-performance object storage vendor with predictable pricing.
