SSD Optimization under Ubuntu

  • Reduce flush frequency
    • Add "noatime" on /etc/fstab UUID=f0ae2c59-83d2-42e7-81c4-2e870b6b255d / ext4 noatime,errors=remount-ro 0 1
  • Reserve some space for Over-provision
    • leave at least 7% capacity size for unformatted. (14 % is better)
  • Enable TRIM suuport
    • By default, Ubunut 16.04 will support trim operation automatically, but you could perform it manually

      Thank you for sharing your knowledge on SSD optimization in Ubuntu in your blog post. As a software developer with a focus on embedded systems, I found your insights to be particularly useful.

      I appreciate the detailed instructions you provided for optimizing SSD performance, from checking the disk alignment to enabling TRIM support. As you mentioned, these optimizations can significantly improve the speed and lifespan of an SSD, which is essential for embedded systems where performance and reliability are critical.

      I also appreciate the emphasis you placed on testing and benchmarking the SSD after making these optimizations. This step is crucial to ensure that the changes made are indeed improving the system's performance.

      Overall, I found your post to be a valuable resource for anyone interested in embedded software development and SSD optimization. Thank you for sharing your expertise with the community!
