"Night and Day"5.0 starson by Ballymoss
Pros: Ultra fast. Large enough for OS and most software I want to run really fast.
Cons: The price is very high.
Summary: I read several reviews and was initially put off by various horror stories about drives arriving DOA, but I eventually bought the OCZ Vertex 3 240GB. I upgraded the firmware to 2.11 and first reaction was that W7 Pro Installed in about 10-12 minutes. I run the Trainz 2009 rail simulator and I found that loading times for a large Route have been slashed from minutes to seconds, and frame rates are incredibly smooth. When I Search my PC for something (like a photo) it is there instantly!
Overall the difference between this and an SSD is "Night and Day".
At UK £351 it wasn't cheap but what the hell? You get what you pay for.
