I was checking Amazon the other day and saw both the 100GB and 200GB versions of the OCZ Vertex LE are available for pre-order. Both drives are next-gen (as of Feb 2010) performance wise and are said to be shipping sometime late February or early March.
I preordered the 100GB Vertex LE from Amazon.com. I’m guessing it will be available less expensively, but I wanted to get one of the 5,000 before they are sold out. It looks like these are going to be the only low-cost SF-1500 controller based drives for awhile, depending on what Other World Computing (OWC) does with their drives.
