Trying to decide what RAID setting to use for my 2x 480Gb SSD Cache drives

 

I see the below will give max space but does this any redundancy?

Single: requires 1 device only, it's also the only way of using all space from different size devices, btrfs's way of doing a JBOD spanned volume, no performance gains vs single disk or RAID1

-dconvert=single -mconvert=raid1

 

 

Thanks

Only for metadata, i.e., you'll lose data if one of the devices fails.
