Been running four of these drives since release. Have had NO problems what-so-ever. Three are in a RAID array and one in a laptop.
Now lets talk about the Vertex 3 they replaced.............
That the Intel 320 is in the same league as the Vertex 3 is all I am pointing out. The OP requested reliability. Out of the three he listed, the CLEAR winner is the Crucial M4.
If you take it a little further, the Intel 320 still has the issue and the Vertex 3 seems to be fixed with the latest FW, so maybe the the Vertex 3 is above the Intel 320. I am only comparing the Vertex 3 (not Vertex 2 or earlier) and the Intel 320 (not a G2 or 510, etc.) just to be clear.
