When is it ok to spin down a hard drive ?

Dear Lazyweb,

My home NAS has it operating system on a usb stick and data on four sata hard disks that I would like to spin down (so they are less noisy and save some energy). But what if I run an rsync on them every 20 minutes ? Or every hour ? Is it better to let the drives running because the spin down spin up cycle will cause excessive wear on the drive ?

When is it ok to let the drives go to sleep ?

I use this /etc/hdparm.conf for spindown after one minute:

root@gwen:/var/log# cat /etc/hdparm.conf
quiet 
/dev/sdb {
        spindown_time = 12
}
/dev/sdc {
        spindown_time = 12
}
/dev/sdd {
        spindown_time = 12
}
/dev/sde {
        spindown_time = 12
}

using bind to block domains

Is this bind usage a good way to block domains on a local network ?

root@gwen:/etc/bind# tail -2 named.conf.local
zone "facebook.com" { type master; file "/etc/bind/db.block"; };
zone "twitter.com" { type master; file "/etc/bind/db.block"; };

root@gwen:/etc/bind# cat db.block
$TTL 24h
@       IN SOA ns1.antwerp.local. paul.cobbaut.gmail.com. (
                  2012082800  86400  300  604800  3600 )
@       IN      NS   ns1.antwerp.local.
@       IN      A    127.0.0.1
*       IN      A    127.0.0.1

Or is there an obvious better solution ?
