Firmware for the Crucial m4 2.5” SSD is being updated from version 010G to 040H.

The m4 is updatable to this new firmware starting from any previous version in a single step.

Version 040H includes the following changes: 

• Improved robustness in the event of an unexpected power loss. Significantly reduces the incidence of long reboot times after an unexpected power loss.
• Corrected minor status reporting error during SMART Drive Self Test execution (does not affect SMART attribute data).
• Streamlined firmware update command for smoother operation in Windows 8.
• Improved wear leveling algorithms to improve data throughput when foreground wear leveling is required.
