FWIW, i converted over to using Storage Groups.
its a pretty simple exercise to convert from the previous multiple-directories
across to storage-groups. (i run a fairly recent mythtv SVN head release).
my storage consists of approx 3.5TB of disk - an original 4 SATA/PATA disks
ranging from 200GB to 350GB and recently augmented with 14x180G FC disks.
i tend to find that its never 'full' and for the most part the 'enterprise
class' disks here are typically spun-down for days at a time.
given the multiple-directories & subsequent storage-groups, i'm amazed folks
persist with LVM/RAID setups & the pain associated with performance bottlenecks
and failed disks.
