Flex-Raid 0 or JBOD
I've recently bought a ReadyNas Duo v2 mainly for media streaming, and have been testing it out with a couple of 2TB I had. It have no problems streaming video etc.. However I did find it slow when c...
In either case (jbod or raid-0) you'd need to recover your data from backup if a drive fails - the only difference is how much data you need to recover.
Using RAID-0 that spans both drives (with a single volume) means that you will lose all your data if either drive fails. JBOD of course only loses the data on the failed drive.
Having multiple drives in the array generally does speed things up, but the main limit you are seeing is due to the 100 mbit network speed. A single drive can easily keep pace with streaming, and your file copies should be much faster once you deploy the new network.
Personally I would go for reliability over raw speed. My media library is on a RAID-5 (xraid2) volume, and is also fully backed up. While it isn't as critical as some of my other data, it is hard to get back (re-ripping, tagging, etc is a lot of work), and there is a lot of it. I figure that if something is worth saving, it is worth backing up - so I don't spend a lot of energy sorting "critical" files from "not critical" files.
