Btrfs performs well on both HDD and SSD. AFAIK, the ssd option of btrfs only affects the block allocation behavior. However, under hybrid combination of HDD and SSD with the multi-device support of btrfs, there can be more interesting optimizations that utilize the physical characteristics of each device. -- Dongjun -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
