SandForce allowed manufacturers to make these 25nm SF-1200 drives out of necessity. There isn't a lot of 3Xnm flash going around these days and it all costs quite a bit more than the new 25nm stuff. I don't think anyone really predicted that performance would take as big of a hit as it did, but it is what it is. For the most part manufacturers were to reduce the final cost of these drives to consumers, but I think the consumer market had already bottomed out before the change to 25nm took place. What we ended up with were 25nm drives using the same SF-1200 controller being sold for the same price as the SF-1200 / 3Xnm drives - around 200 USD for a 120GB model.
The performance is obviously down quite a bit with the new flash and the drives are pretty much guaranteed to not work as long as their older technology counterparts. Manufacturers have come up with nice marketing names for these new drives like this model, the PLUS, but in reality RunCore should have dubbed this one the Pro V Minus since it isn't as fast as the previous generation.
Hopefully RunCore is able to price the Pro V Plus at a competitive point that is much lower than the older Pro V. That is really the only reason anyone should look to buy the Plus; the price has to be right and being right means being very low. I don't have any pricing information on the RunCore Pro V Plus and maybe that is a good thing since we can just leave it at that. Sometimes I can't help myself, though, and think that a RunCore Pro V Plus 120GB priced between 140 and 150 USD would be a good price point. Anything higher and you might as well buy a SF-2281 controlled drive paired with asynchronous flash for 200 USD.
