My Mac currently has an OWC Mercury Pro Extreme SATA 2 SSD. It's one of the fastest SATA 2 SSDs out there. But, it only has 115 GB of storage and I find myself running out of room. This spring I'll be buying a new MacBook Pro. Right now my top choice of SSD is a 240 GB Corsair Force Series GT. It uses a Sandforce 2200 controller and a SATA 3 interface. It's nearly identical to the OCZ Vertex 3 and OWC Mercury Pro Extreme 6G, but somewhat cheaper. Is there any reason for me to hold off on buying a new SSD?
