Crucial worked really hard on their new firmware and the results speak for themselves. In almost every test we saw improvements in performance. Some of the gains were larger than others, but it's not like they just went in and overclocked everything like a desktop processor. The Crucial performance level has been raised, but our real world tests with data on the drives show that Crucial still has a way to go before taking the performance crown away from SandForce.
That may sound a bit harsh, but it is also a bit misleading too. It all depends on what you're looking for in an SSD. Crucial hasn't had nearly the number of complaints about long term stability or the famous Drive Dropout Issue that is associated with SandForce SF-2281 controlled drives. To be fair to SandForce, not everyone is having the issue, but if you have it you could care less if anyone else does; it is a problem you have, a 100% failure rate in your eyes. For Crucial that is a big selling point and a big reason why we are still m4 fans even though they might not be the absolute fastest on the block.
Enough about updates and comparisons - did you see how fast the Crucial m4 512GB was? The 512GB version of the m4 is faster than the 256GB and the 128GB. I expected the m4 512GB to be faster than the 128GB and a little slower than the 256GB, but that wasn't the case. It is now clear that the 512GB is the Crucial m4 we've always wanted.
When the m4 product line was launched several months ago the 512GB model was barely on anyone's radar. It was sort of like an exotic car; you knew of its existence, but the price was far from your target budget. Luckily there are reviewers out there that can't let go of their dreams. At the time of writing we found the Crucial m4 512GB available online for as low as 574.69 USD. Don't get me wrong, it's still a lot of money, but it isn't 1,000 or 1,200 Dollars like it once was. Unlike our dream cars that just get old and slower with age, the m4 512GB actually got better after the new update.
There is of course one fact that trumps everything I've said on this page. IT'S 512GB of SSD STORAGE CAPACITY! Better yet, it's twice the SSD storage capacity of the 240GB SandForce drive you were thinking about buying at less than twice the cost. The Corsair Force GT 240GB that we reviewed recently costs 459.99. So for around 115 Dollars more you could double your capacity and still have really good SSD performance.
