Michael, Thanks again for your comments, they are very helpful. I have been googling RAID1 and LVM and finding lots of good information. I really like your idea of a RAID1 for the two SSDs. Does it matter if one is msata and one is not? I am trying to decide on the merits of using LVM with the RAID1, since I only have 1 disk and I normally don't partition it so I don't have to worry about running our of space until the disk is almost full. Could you explain to me the benefit of using LVM + RAID1 for these two drives? How would you partition the drives? My current drive has about 420 GB of data in /home, about 9GB in /opt, and some misc stuff in /var, all of which I need to transfer that to the new system. Thanks, Mark P.S. One benefit of using both LVM and RAID1 is learning something new! ;) On Wed, Sep 3, 2014 at 12:33 PM, Michael Butash wrote: > I really never hit any io constraints on disks honestly since using > ssd's.
