4TB on S3 Deep Archive: $3.96/mo to store, $360 to restore and download over the internet 4TB on B2: $20/mo to store, $40 to download 4TB on Digital Ocean: $80/mo to store, $30 to download
Yes, it feels almost extortionary to have to pay that much to get your data out of AWS. But depending how long you store data for, it can end up being the cheaper option: you're just gambling on how likely you are to actually need to download it.
DO is great for small personal projects, but, I wouldn't run a fortune 500 company on it.
Snowball/snowcone, US East
$0.03 per GB ~-> $300 per 10TB
If you're buying disks at scale that's almost the cost of the disk.
Network egress
$0.15 per GB
$0.08 per GB (>150TB/month)
It makes sense for the occassional transfer so you're not paying for expensive EBS storage for stuff you don't need cloud access to.
The other big part is pricing. AWS charges $ 0.09 per GB for outbound transfer, so getting 8 TB of data out of AWS via the internet costs over $ 700. Doing it through Snowcone costs around $ 300 + shipping.
Reasonable use-case would be transferring video material or high resolution sensor data.
