I’ve had a Storm on Demand account for about a year now, in an effort to get away from the GoDaddy Virtual Dedicated environment. The Storm on Demand service, by Liquid Web, is a totally scalable hosting solution that can grow with you as your storage, memory, and bandwidth needs grow.
One of the huge benefits has been their customer service. Any time I need help with server configuration I can just call them up. Their techs are very knowledgable, will spend as much time as it takes to help you out, and if they don’t know the answer, they find someone who does. I know it sounds simple, but I can’t begin to tell you the amount of disinformation I’ve received from other companies when their tech wants to hide the fact that they don’t know the answer.
Their pricing structure is totally based on usage, and since you can scale up or down at any time, nothing goes to waste. Storm on Demand accounts are billed by the minute, which can be useful if you need a temporary bump in bandwidth or storage. Check out their plans and pricing here.
I don’t have any benchmark data, but I can tell you that the overall speed and performance of a Storm on Demand account blows away your typical shared hosting account.
