Oh, more fiction:
Because SATA uses point-to-point connectivity, the scaling available with SAS controllers is not possible with SATA controllers. SATA drives must be connected on a one-to-one basis with the SATA connectors on the controller – i.e, a fourport SATA controller can connect up to four drives, an eight-port SATA controller can connect up to eight drives, etc. This means that the number of drives needed must be known prior to purchasing a SATA controller, or additional hardware costs will be incurred.
Ignoring port multipliers (hubs) again there. A SATA hub can connect up to 31 drives to a single SATA port, or up to 248 drives per 8-port PCI(X/e) controller card. I don't know if anyone currently sells a 31-port multiplier, though.
