As a provider we provide full SSD hosting. This is more expensive but great for performance. I have an idea to split space for web and e-mail so I can sell packages with F.E. 5 GB of SSD webspace and 25GB blocks for e-mail on HDD. Technically this is already possible but the problem is the quota. I would really love to see a separate possibility for web and email quota. Also then it would be nice if you just could select a partition/mounting point just like with the system backup.
