I think I should set the record straight here.
Despite what you may have read on other sites, the facts are these, regarding the OCZ Vertex 4.
The OCZ Vertex 4 uses a CUSTOM and proprietary Marvell controller, but the firmware is 100% Indilinx.
Regarding the SandForce SF series SSD controllers, and specifically the OCZ Vertex 3.
OCZ were first to market with an SF-2281 processor, a processor that clearly hadn't been fully validated by SandForce. So naturally OCZ took the brunt of the flac. OCZ also sells more SF based SSDs than all the rest of them put together, so again put themselves in the firing line.
The SF BSOD problem was fixed months ago. That doesn't mean that no one is having a problem. But then again, a quick google on Crucial, OCZ, Corsair, Samsung, Intel, with BSOD added to the search will bring up multiple results of people having problems of one sort or another.
To single out just one company is wrong.
