That image may bear a remarkable resemblance to a DIMM but it is indeed an SSD using the PCIe M.2 connector.  The models that The SSD Review saw came in both M.2 and SATA versions with read and write speeds of up to 1.8GB/s over a PCIe 4x connection which is more than a little impressive.  They've taught this new controller another trick as well, DuraWrite Virtual Capacity could triple the storage available on an SSD virtually, a 128GB drive could store up to 384GB.  Hopefully we will get a more in depth description of how DVC will work in the near future.

1 notch PCIe X4 = 2000MB/s
2 notch PCIe x2/SATA = max 1000MB/s or 550MB/s

"Since first discovery of the next gen LSI SandForce FSP , we have seen this controller shed its ‘ Codename Griffin’ skin and receive official validation as the new LSI SandForce SF-3700 Series flash controller, indeed capable of top SSD performance speeds of 1.8GB/s. There are a ton of questions that remain, however. Why hasn’t it been released? Why haven’t we seen thorough performance benchmarks? Are there heat issues with the controller? Is it possible, like folklore describing the Griffin with its head of an eagle and body of a lion, that the SF3700 family is myth and something that we may just never see? Let’s tackle these questions one by one, all the while showing you some early examples of what various LSI SandForce partners have to offer."
