I am with my immediate family. Despite the lack of broadband in the
house, thanks to Sprint PCS EV-DO and ssh, I am still able to
benchmark various RAID configurations on a massive new storage
server I got up and running yesterday. Once I figure out the best
chunk size to use, I'll use it for both MythTV storage and, of course,
as a backend (first slave, and perhaps as primary later).
Meanwhile, I periodically track my MythTV frontend/backend's current
status through MythWeb.
 So far, with a JFS-on-RAID 6-with-512K-chunk configuration, the
best I've seen is
$ time dd if=/dev/zero of=80gb bs=1024k count=80000
83886080000 bytes (84 GB) copied, 859.941 seconds, 97.5 MB/s
$ hdparm -Tt /dev/md0
Timing cached reads: 10064 MB in 2.00 seconds = 5037.11 MB/sec
Timing buffered disk reads: 856 MB in 3.04 seconds = 281.81
