As far as I know, the AData SP9xx series uses SandForce SF2281, which may not be a great choice for a laptop which may be put into a sleep state.
My personal choice would be one of the following.
OCZ Vector 150
Samsung 840 EVO
Crucial M500 or M550 (M550 if available)
OCZ Vertex 460
Toshiba HG6, if you are prepared to wait a couple of weeks on availability.
