I'm looking at deploying SeaWeedFS but the problem is cloud block storage costs. I need 3-4TB and Vultr costs $62.50/mo for 2.5TB. DigitalOcean $300/mo for 3TB. AWS using legacy magnetic EBS storage $150/mo... GCP persistent disk standard $120/mo.

Any alternatives besides racking own servers?

*EDIT* Did a little ChatGPT and it recommended tiny t4g.micro then use EBS of type cold HDD (sc1). Not gonna be fast, but for offsite backup will probably do the trick.
