I'm back to using single large drives (with spun-down or offline backups) at home 'cos I don't like the power usage and noise of lots of raid drives. few *3tb is enough - I don't need 24tb always online.
essentially I'm doing raid1 but with very delayed and power-friendly mirroring, and am prepared to do a fair bit of work and/or lose some data when I get unreadable sectors.
Are you doing that manually (e.g. a daily cron job calling rsync or dd), or do you have something like mdadm --write-behind=BIGNUM?
