3 years ago I wanted to upgrade the HDD in my 2007 Dell Latitude D620. I never really used it but every now and then I fired up the Windows machine, it was just painfully slow. I popped the OCZ Vertex 2 in there which people complained about speed vs other brands. Three years later it's still a great job and Windows runs super fast on that machine. I sprung for a top of the line SSD in my desktop but I don't know if I would again unless I had a specific need for more speed.
