New Client SSD Firmware—Even Faster Starts and Lower Power Use

By Jon Tanguy - 2012-09-26

One of the advantages of owning a Micron (or Crucial) SSD is that you often benefit from the continuous improvements we roll in to win new business and meet future design requirements. That’s certainly true with our latest C400/m4 firmware release, which provides multiple speed and power upgrades. This is optional firmware, but users who choose to install this update will benefit from the following enhancements.

  • Faster Boot Up
    Thought your SSD boot times were already great? To meet demanding “instant-on” specifications for Ultrabook™ devices, we improved the Client SSD time to ready—the sliver of time between when the power button is pressed and when the drive is ready to accept commands. For our 512GB SSD, we shaved 60% off the maximum time to ready—nearly a second and a half. Total boot-up time is controlled by lots of other factors, but for machines that boot quickly, extra seconds make a significant difference. If your boot-up is already in the 8- to 10-second range, it's a noticeable improvement.
  • Faster TRIM
    The average user can’t measure this, but we’ve improved the efficiency of how TRIM works on the drive. (TRIM is the Windows utility that cleans up after deleted files—an important function for SSDs).
  • Windows® 8 Certified
    This latest firmware has been officially certified to work with the upcoming Windows 8 OS (older firmware revisions can work with Windows 8; they’re just not certified).
  • Better Power Management
    We made some power consumption improvements as well. The first change corrects instances where some systems would bring the drive out of standby prematurely, drawing power unnecessarily. We also identified certain systems that were drawing power during standby. The second change (isolating a particular power pin during standby) stops that power draw. For affected systems, this can extend battery life significantly.

The new firmware update utilities are available on Please post if you have any comments or questions. As always, if you’re a Crucial customer, you should download the update at
