So it takes a slot away from the system.
Why do that when there are usually at least 4 SATA connections on a MoBo? The only reason that could justify this product is if its xfer rate exceeded SATA by a significant margin.
I wonder how much of the potential SSD performance is eaten up in translating between the FLASH and an interface system designed around a rotating disk of metal. It has been expedient to use an HDD emulator to get data in and out, but maybe the time for that is past?
The mSATA sounds like a good step in the right direction of better optimizing for the solid state media, but perhaps now might just be a good time to develop a new interface system created from the ground up to take best advantage of solid state memory.
This sounds like an evolution of Intel's "Turbo Memory" that seemed to have a similar function and also utilized Nand. (My 2 year old Lenovo is equipped with 2Gb of Turbo memory.) However, I think that it was difficult to get much of a premium for it when thought of really as a cache for the hard drive. I believe it ended up being a "throw in." I think that they are hoping to get some of the SSD revenue stream with lower performance memory..
