SSD’s, Journaling, and noatime/relatime
Read OriginalThis technical article investigates whether the common advice to avoid ext3/4 journaling on SSDs is valid. It details an experiment measuring write overhead during a git clone and Linux kernel compile, comparing ext4 with and without a journal and using the noatime mount option. The results quantify the performance impact, showing noatime significantly reduces journaling's extra writes.
