> last I checked RAID 5/6 is basically asking for data loss with modern drive sizes This is a debate I would love to see with people who have experience. Since I've seen individuals speak with authority on both sides. I get that if you have a basic array of disks humming along with a big-ass ext4 partition, once one drive dies, the risk of the other drives being riddled with errors is huge. But what if your array is both (1) using ZFS or BTRFS (with data checksumming) and (2) has scheduled full-disk data scrubs once a month or so? Wouldn't you catch the initial recoverable errors quick enough? |

Not always no.
I've had drives reporting failures for months that zfs scrub keeps fixing, tons of time to get a spare.
But drives also fail suddenly with no history of zfs or SMART errors.
