Ok, since you have been reading this thread, I'm guessing you also know that Plextor M5S are currently reliable and best buy for now (look carefully).

As for the 3 SSD you've mentioned, besides of Intel 330 that already discontinued in some countries, the rest I think it's okay. Sandforce controller were bad in the previous SSD but now they have been some improvements ( hope so ). But lets face it, not everybody willing to gamble right? 

In the end, despite all the improvements that SandForce had made, I'm still sticking with Marvell, knowing that I prefer reliability rather than performance, and not much of a benchmark enthusiast.
