Hi, I'm from Brazil and I'm looking for a SSD. I've been reading a lot about it, but I don't have a conclusion yet. Well there are just a few models on my country, so I need help to choose one of these models: OCZ Vertex 4 256GB, Intel 520 240GB, Kingston HyperX 240GB, Corsair Perfomance Pro 256GB and Corsair Force GT 240GB. OCZ, Corsair and Intel cost about $500, Corsair about $575 and Kingston about $450. Yeah, the prices are right, all electronics, cars, etc, are very expensive here due to taxes... I've read about some problems with SandForce Controllers, is it still happening? Except for Corsair Performance Pro (Marvel Controller) and Vertex 4 (Indilinx), all of them have SandForce Controllers. Thank you everyone.
