Striped LVM on RAID5 is a nice, flexable way to go.
If you set the individual raid stripes at an I/O page
(normally 4K on linux) and then stripe across the
PV's the I/O gets spread nicely across plenty of paths.
Using a stripe == I/O size avoids the "write penalty" in 
RAID5, the Raid Controller and drives do a nice job of
buffering and the whole thing should work nicely.
