I was looking at the OCZ Vertex 4, but i heard it had a firmware issue that made you completely clear it to upgrade and that destroyed all your data. This is for a completly new computer build so I dont want to install windows 7 then have to reinstall it. I want one but im not sure if this problem is still prevalent or if it was fixed. I need to know urgently because of the sale that's going on for the 256gb version of it. Thanks
