Crucial M4 SSD Firmware Update (0009) Posted – Tests Display Definite Performance Increase

Crucial has posted a firmware update (0009)  for its M4 line which can be downloaded at Crucial.Com by M4 owners.

The good news is that the firmware provides significant performance increase for all capacities of the M4 SSD and Crucial has all capacities of their M4 SSD on sale now at great prices.

We initially thought this to be a typical f/w update and subsequently upgraded and tested our  Crucial M4 512GB SSD without thought.

The Vantage HDD Suite score jumped from 63076 to 68543 total points.  This was totally unexpected and great to see!

Our next step was to take a closer look at Crucials description of the update.  With the number of significant improvements, Crucial could have easily raked in the cash with a new M4 premium version SSD.  This is direct from Crucials note to us:


  • sequential read speeds by up to 20%
  • PCMark  Vantage benchmark scores, which results in an improved user experience in most operating systems


  • throughput performance
  • write latency for better performance under heavy write workloads
  • compatibility with latest chipsets
  • intermittent failures in cold boot up related to some specific host systems


  • users with faster boot up timescompensation for SATA speed negotiation issues between some SATA-II chipsets and the SATA-III device

We thought it only fair to show you first hand what we are seeing.  We tested our Crucial M4 128GB SSD before the upgrade (left) and then after we applied their new ver. 0009 firmware (right).  All tests conducted are fresh results and were done within an hour.




A quick click on the Vantage tests will bring each up full size.  The Vantage HDD Suite Score jumped from 61772 to 66432 total points.

In a nut shell, this is a great firmware update from Crucial as visible improvement is shown in any and all tests conducted.  The only downfall is that Crucial hasn’t discovered a simpler Windows based solution for the update.  The upgrade consists of  creating a bootable disk from the firmware download, changing your computers bios to IDE mode, rebooting into the DVD and following the instructions to upgrade the SSD, changing back to AHCI and rebooting back into your system.

Can it be a bit scary for the novice? 

Sure it can but Crucials instructions will help you right through it.

Is the upgrade worth the trouble?
