Hello, I've just bought two new Seagate SATA drives and a Promise TX4
SATA300 controller. The disks and the controller is working fine but I'm
a little confused how I should setup them.
First of all I'm running FreeBSD 6.1. The disks are two 320 GB drives
who I'm going to use for storage. Backups, movies, music etc.
I've read the handbook about adding new disks and I've got them setup
but here are my questions.
1. Should I use soft updates or not on the new disks? The handbook
doesn't mention anything about using -U to newfs to setup soft updates.
The installer is using it on the system disks but is it a bad idea to
use it on storage disks or why isn't it mention in the handbook?
2. Is it a bad idea to use tunefs -m 0 ? I don't need any space reserved
for root at the disks but the man page mentions that I'll loose
performance when using -m 0. Will it be so much that the extra space
isn't worth the performance loss?
3. Should I use tunefs -o space or time? I guess space is the way to go
but again how much of a performance loss is there?
If you replay to this email could you please CC it to me as I'm not

Thank you for you help.
