1RAID capacities are actual usable storage amounts. The RAID parity and spare drives are not added in to the storage figure.

2 Figures are approximate minutes. Some servers draw more power under heavy load.

3 Subscriber estimates are based on combined web and e-mail storage average of 200MB to 250MB per subscriber, dial-up speed of 50kbps, broadband speed of 1Mbps, 20% web traffic, instantaneous usage of 3%, and 30% proxy efficiency. Your actual subscriber capacity will depend on the speed of service, services offered, and many other variables.
