I've been using btrfs for about two years on multiple devices.I am planning to test some btrfs configurations on a HDD (Single platter) which has non reliable sectors. A dozen of sectors on the HDD are sometimes not readable.Would there be any difference in terms of data integrity and overall read and write speed in these setups:1 TB HDD-1 TB btrfs partition created with `mkfs.btrfs -d dup -m dup /dev/sda1`1 TB HDD-500 GB partition-500 GB partition--500 GB btrfs Raid 1 `mkfs.btrfs -m raid1 -d raid1 /dev/sda1 /dev/sda2`
What is the difference between btrfs raid1 and btrfs -m dup -d dup on a single device
btrfs;raid1
