I have bought 2 Crusial M225 64 disk and have been very happy for them, but I have discovered that it has trouble handling big files. I experienced many times that my games with big files ->2GB became corrupt many times. When I placed my files on a normal disk the problem went away. The only conclussion about this for me was that I do not trust my SSD's to handle very big files. I must say that I am running my laptop on one of the drives now with new firmware (Ver. 2030) and is very happy about it. have not seent he issue yet on this one.
