See my sig for microSATA SSDs. The Sandforce units would be the fastest. Problem is that 1.8" microSATA appears to being phased out by mSATA and 7mm 2.5" SATA with few manufacturers giving new microSATA SSD options.
A workaround would be to obtain say a Runcore T50 (SF2xxx) and a microSATA connector, then solder the 9 wires between them to adapt it.
