While Plextor released a new firmware yesterday, we missed that Crucial has updated the firmware of their M4 series two days ago. The new 040H firmware is available for the 2.5" SSD and the mSATA drive firmware update has version string 04MH. The firmware improves how the drive deals with sudden power outage, mainly reducing the long boot time that can be caused by this.
Also wear leveling is improved, the technology that should keep your drive in an optimal condition as long as possible. You can find the entire changelog here. Users who want to upgrade can download a tool to flash the new firmware directly from Windows or you can download a boot image.
