Crucial SSDs are... meh. I thought they were good, but then I realized that a lot of the random little crashes and sleep glitches were due to the drive. I had the mx100 in my desktop randomly drop out the other day (that model has that known bug, still hasn't been fixed). Then, the laptop crashed shortly after resuming from sleep (mx200). And Thinkpads don't seem to like the drives. Crucial really needs to get it's sh*t together, firmware-wise. 840 evos slow down excessively over time, b at least they don't stall and crash Windows (though neither is even remotely acceptable IMO). Fwiw, I stuck a Toshiba Q series pro 256GB in the laptop - seems like the type of boring, not marketed, just works drive that an OEM would use. Working fine so far. And I ordered a Sandisk Extreme Pro on the way for the desktop, so we'll see how that goes.
Crucial RAM has been rock solid for me though, in multiple machines. Same with G.skill.
