[mythtv-users] Best use of 2 500G drives in FE/BE system

So,  I got all my new hardware and I want to partition my new Gentoo MythTV box.  My case only supports 2 drives, so I have 2 500G SATA drives in there.  Now, here's my question.  Do I...

a) create /, /usr, /var, /tmp as Raid1.  Then use the rest of the disk on both disks to be put into an LVM volume and use that for /video.  In this scenario, if a disk dies my system is still fine, but I'm going to lose about half of my recordings

b) Do the same thing as a), only stripe the disk remainder before putting it into LVM.  I still risk losing recordings, but I'm thinking that this might be faster than straight LVM.  Or, does LVM stripe?

c) Mirror both disks, and then do LVM on top of the RAID1 mirror for the /video partition.  This is nice and safe, but then I don't get buckets and buckets of recording time

On my old system, I had a single 80G IDE drive (for /, /usr and all of that) and an external 250G usb drive (for /video).  I was always hovering around 90% on the /video partition.  So, I suppose that 400-450G will be a big improvement, but I'm drooling for ~900G.
