Yeah, there is definitely something to be said for well executed appended JBOD, but I like having a little having more control over what's actually going on. A well executed striped RAID (0,5,6,etc) will also give you a nice performance boost, which should increase as more drives are added....not the performance really makes much difference in my setup since I have a 1Gbps bottleneck at the network interface... It is much more of a pain to implement and manage a good RAID array, but I think it's worth it. Plus, since I use RAID-5, if any one drive in my array dies, I don't lose any data at all (assuming I get a new drive and populate it before any more drives fail). That's saved me a lot of trouble once already; I had one of my 1.5TB drives die a few months ago, and it was then that I stopped feeling bad about 'losing' one drive's worth of storage space (due to the RAID-5 parity)...it's a lot better to have to buy one more drive than to have to restore 1.5TB of data...if it's even possible to restore that data from another source.
