Samsung are good, but I have Intel 520 180GB. It's a matter of choice.
I haven't had any problems with the Sandforce 2281 controllers. And the whole "compressible vs. incompressible data" issue doesn't bother me.
I've had 2xOCZ Vertex 3 60GB in RAID 0, and decided to go without RAID. No regrets!
From what I understand there's not much difference to the user if you're not hardcore into this stuff. I will be using it just for gaming and regular use, so upgrading from a HDD to an SSD will give all the 'wow' effect I need probaly. Guess I'll go with the Samsung 830 Series then as it seems to be one of the better for a good price.
