Micron and Crucial have released a firmware upgrade for the Micron C400/Crucial m4 and mSATA SSDs, providing multiple speed and power advancements. This upgrade is another example of the advantages of owning a Micron or Crucial SSD—end customers often benefit from the continuous improvements we roll in to win new business and meet future design requirements.

 

While the firmware upgrade is optional, users who elect to install this upgrade will benefit from the following enhancements:

 

· Faster boot-up times We improved time to ready—the sliver of time between when the power button is pressed and when the drive is ready to accept commands.

· Faster TRIM We improved the efficiency of how TRIM works on the drive.

· Windows 8 certification The new firmware is officially certified for the upcoming Windows 8 OS.

· Better power management We increased power efficiency during standby mode, which can extend battery life significantly.

The new firmware update is available now at our Firmware and Downloads section here.

**UPDATE**

In response to comments about systems using the new UEFI BIOS, we’d like to clarify some concerns that have been expressed by users. Unified Extensible Firmware Interface (UEFI) is a new BIOS architecture shipping with some systems. Even though our firmware code itself is compatible with systems utilizing the UEFI BIOS, we issued our original UEFI note because 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 users will retain the firmware version they started with. Windows will then restart normally. If this sequence occurs, customers cannot upgrade to this firmware version at this time. However, it’s important to note that in this instance they’ve done no harm to their system or data. For those customers who have already successfully updated their firmware, rolling back to older versions is not necessary and not recommended.

We chose to make this firmware available because the vast majority of Crucial customers are not using UEFI-based systems, and we wanted to get the benefits of this upgrade out to the majority of our users. We are working on UEFI-compatible tools and expect to have them available within the next month.
