Compatibility Notice: The Crucial Adrenaline Solid State Cache Solution uses a Crucial m4 SSD to cache data and boost system performance. While the firmware update on this page refers to the Crucial m4 SSD, it is compatible (and recommended) for the Crucial Adrenaline.
WARNING: The firmware update process is done entirely at your own risk. Before initiating the update process be sure to backup or make copies of all important files. If the firmware process is interrupted your solid-state drive may not function properly.
UEFI-based Systems: During validation of this firmware update we noticed instances where our update tools do not recognize the SSD with some systems using UEFI. The target device is not recognized as an updateable device during the reboot process. If this happens, the firmware update will not occur, and you’ll retain the firmware version you started with. Windows will then restart normally. If this sequence occurs, you cannot upgrade to this firmware version at this time, but you’ve done no harm to your system (or your data).
If you have a Dual Boot system we recommend using the Manual Boot Process as opposed to the Windows Update Utility.
If you have more than one m4 in your system, note that the Windows Update Utility will update all eligible drives automatically. With the Manual Boot File you will be prompted on which drive(s) you want to update.
If you have questions or need assistance, please contact our Technical Support department.
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.
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.
