Just to share my experience with 256GB Liteon LS9. First it's small and my desktop bracket is too big. Only screwed to one side of the bracket. Second speed test it didn't reached the published speed. Finally found out that my old MB Marvell SATA slot doesn't support the full capability. Switched to Intel SATA slot and it did reached the published speed.

If you do have the budget, it's worth to tryout and I do feel some increased speed in windows bootup and loading of applications.
