I'm looking for a diskspace of possibly 1TB online
Edit: my idea is to use it like as an external harddisk for everyday stuff. Encrypt the disk, put my filesystem on it, mount it as external drive kinda. Never worry about backups or lost data etc, as the provider would take care of it
This is only slightly related - I lost a small number of files with DreamHost object storage, and they were charging more than S3 per GB.
So, I agree you usually get what you pay for, but also make sure the provider is all-in on the product. I think DreamHost really isn't interested in their virtualized/cloud offerings.
