just as a benchmark, my current backend has 4x300GB drives, two SATA
two PATA (on different channels). setup in a RAID10. I've got 2 QAM
tuners, a PVR150 and a firewire connected cable box. I'm capable of
recording on all of them, and watching two HD streams without issue.
I'll soon be adding another 2xSATA drives to this and probably
switching over to RAID5, hoping to gain some space and perhaps some
speed.
All this on a consumer grade MSI motherboard with onboard controllers.
So my point is, it should work fine, so as Mike says, try ditching the
LVM, go with software RAID or Storage Groups as your setup allows and
your needs warrant.
