To be honest I don't know why there is so much commotion about it.
I wrote on the V300 thread that unless Kingston specifically indicated sync nand, it was not bait and switch. I'll say the same here, unless PNY specifically indicated SMI controller, it is not bait and switch.
Even with a different controller, I would worry more about the NAND used. Something that those "tech" sites are failing to mention is that the Optima is value line of PNY's SSDs, so they should have picked on where cuts were made vs the XLR8 line. If we enthusiasts know about products lines among brands, the "tech" sites should be paying closer attention that we do. A value line performing as well as the premium line? What is the catch? how does it affect the premium line? Is the great performing value line sample representative of final production? Those are the questions the "tech" sites should be asking!
I think cuts on the optima are more than just the controller, I would bet the optima also uses inferior NAND. The SMI optima performs better than the SF optima as I suspect the SMI controller is better at working with the inferior NAND. The SF-2281 in SSDs with premium NAND performed great, just see the reviews of the Sandisk extreme, Kingston HyperX 5k (original hyperX) or OCZ Vertex 3 max Iops, all of them among the fastest SSDs of their time. All of them had toggle NAND, and I would bet money on any of them handily beating a current SMI based optima, so it is not "is slower because of the SF-2281"
