Hi, I purchased an OWC 115gb Mercury Pro Drive. I saw a "Comparison of SSD Data Write Speed Estimated Over Time" on the OWC site and wondered how long SSD data blocks can be written to. I have about 85 gb free and expect to fill that free space almost every week or two before moving the data to the 5400rmp 500gb onboard Apple drive. I am working primarily with large Nikon RAW images(12-20mb each) and some Nikon movie files(50mb-400mb). I know SandForce is supposed to prolong the drive life but how long are SSD's to surviv ewith constant writing and reading of data to almost max drive capacity. Also is this true or more marketing drivel: "Unlike most SSDs on the market today, the Mercury Pro family uses advanced SandForce DuraWrite wear-leveling and block management technologies to keep Read/Write performance at peak while others see performance fall." Thanks.
