" ... Crucial made available a firmware update that significantly changed the performance profile of their M4 SSD ... the Crucial drive offered more consistent performance with all data types, thanks to the characteristics of its Marvell-built controller, which handles highly compressible and non-compressible data similarly".

Recommended Mid-Range Hardware Award
"The M4 also did a better job of keeping its performance in our "used drive torture test" but I won't pay much attention to that test, as it doesn't replicate real performance as well. That being said, the M4 won most overall tests that use relatively common levels of compression. That includes 4K IO transfer, and both versions of PCMark." Full review

"The Crucial m4 128GB is a solid buy that will increase your user experience by running your daily tasks quickly...What we learned today is that the Crucial m4 is a real competitor to the SandForce SF-2281 controlled drives with 25nm IMFT flash....What we are left with is a next generation SATA III SSD that is more than fast enough for nearly all users and a very good value when compared to the competition….The Bottom Line: The Crucial m4 128GB is a solid buy that will increase your user experience by running your daily tasks quickly. If you're buying the drive for a desktop don't forget to add a bracket." Full review

"As you can see, the Crucial M4 was by far the least expensive drive looking at its cost per GB. If you want a high capacity drive and work with lots of incompressible data, the M4 is a fine choice." Full review
