A fragmented ssd doesn't come with the penalty of head seek latency or rotational latency, both of which increase with fragmentation on rotating media. I'm not sure what the equivalent is for SSD. Different SSD's are doing many different things behind the scene; even when not read or written to by the file system. This is one reason why TRIM is questionable. It helps for some devices and workloads, and not others. If you check mount, if btrfs detected from the kernel that this is non-rotating media, it should have mounted it with the ssd option. The other mount option possible, which is manually set (and unsets ssd) is ssd_spread. https://btrfs.wiki.kernel.org/index.php/FAQ#What_is_the_difference_between_mount_-o_ssd_and_mount_-o_ssd_spread.3F Chris Murphy-- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
