Crucial has released new firmware for the m4 series solid state drives. The update is only for the sata models and should not be used for msata models. Version 040H brings no critical improvements and this firmware is therefore marked as optional by Crucial.

Firmware Update Notifications

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

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

Do NOT use any other m4 firmware update for your 2.5” SSD such as the 04MH firmware for the mSATA form factor.

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.
