Block Storage volumes can scale from 1GB to 16GB
Not really what I was looking for...
Web compute server hoster DigitalOcean is adding block storage to its cloud-based Droplet servers. Digital Ocean offers Droplet virtual servers in the cloud for $5/month to $80/month depending on their configuration. The entry-level is 512MB RAM, 1 CPU, 20GB SSD and1TB transfer. At the $80 level you get 8GB, 4 CPUs, an 80GB …
The resizing model at DigitalOcean works like this : you can either upgrade your instance permanently which also (RAM , vCPU and transfer limit change aside) increases its storage in 10GB steps (smallest instance is 20GB then 30GB etc), or you can upgrade other parameters (listed above RAM, vCPU and transfer) leaving storage unchanged, which will allow you to downgrade later (so called flexible model). The addition of block storage means that you can upgrade in flexible manner and still extend your storage, simply by buying extra device. Which you can release later if you no longer need it, alongside with downgrading your instance. Neat.
