treebeard Posted March 3, 2025 Share Posted March 3, 2025 Greetings everyone. I'm having this issue where all my drives that are formatted as either APFS or HFS+ are very slow when writing small files to the disks. Be it internal NVMe's or external SATA, these filesystems perform very poor in this situation, compared to when they are formatted exfat or even fat32. In the Amorphous disk tool, the 4kib write tests get only about 10 and 5 mb/s. The 4kib read speed as also a bit slower at about 60mb/s, however this one is not as painful. I'm wandering if anyone has encountered this and knows of a solution. Tested on Kingston A2000, Samsung 970 Evo and Samsung 860 Evo (via USB-C enclosure).
