"The Crucial m4 needs little introduction since it is one of the two most anticipated SSDs of 2011. The truth is that most of you are planning on skipping the next handful of pages to get right to the benchmarks. Don't do that! Take everything you've already read about the Micron C400 / Crucial m4 and toss it out of your mind, because mumble - mumble - mumble isn't exactly accurate. Let me explain with swollen tongue.
The latest version of the 88SS9174 controller is the BLD2 and that is what Crucial has employed for the new m4. We've had just two days to try and unravel the new 88SS9174-BLD2 with a single example of this controller. Our sample drive is not a retail product and comes in the form of an OEM style Micron C400 with a Crucial label attached. The M400 is the exact same hardware, programming and firmware as the Crucial m4 and our testing has indicated that this will be the first retail m4 drive that will hit the market in April."
