SSD SandForce in MSAT

The MSAT, mainly driven by a standard Intel Will he finally "take" among manufacturers? Computex can believe with reference designs for SSD-based controllers SandForce. MSAT is the umpteenth variation of the SATA interface, in a very compact physical format. The SSD makes MSAT resume form (and connector) card Mini Card, PCI-Express Internal laptops.

MSAT SSDs are very similar visually maps Wi-Fi laptops, but are incompatible: the Mini Card interface line PCI-Express and USB 2.0 while the MSAT works SATA 3 Gbit / s. Currently, the few machines that accept MSAT MSAT SSD in the slot, but Intel has shown that it is possible to make hybrid connectors, capable of adapting to the card inserted.

Currently, there are only few SSD MSAT: the Intel X25-M and Intel 311. But the reference models "SandForce" expected to see rapid flowering patterns among manufacturers. Both models use the controller SF-2281, like many of SSD, but the first uses of conventional memory and works on 4 channels, while the second uses memory in BGA (more expensive) and work on 8 channels.

4-channel models are models of entry-level memory ONFI Classic, which will not exceed the 200 MB / s, while the 8-channel versions are close to the usual models. Like interface limit to 300 MB / s and the MSAT is ultraportables, the speed is not necessarily a problem. Remains to be seen when the SSD and compatible computers MSAT will land mass, the current product is usually delivered directly into a SSD Intel.
