RAID setup?

[JET]

The PS3 is just used as a media player because I don't have a 2nd HTPC. My files are so huge because I only play HD movies at full frame rate. 18+GB is full bluray quality. This part I do know a lot about, check the frame rate on the supposed 1080p movies if they are under 5GB. I play them on a 50" and anything under 3GB looks like crap. You can also tell the difference between a 8GB file and a 16GB, just like an upconverted DVD vs a Bluray.

I'll have to explore the set top boxes some more, it looks like there are 17 models out there now.

It looks like RAID 1 would be the best option, but I think I might just get a JBOD box and just do a backup once a month. With RAID 1 I wouldn't be able to unplug the backed up drives, would I? I only want them running when I do a backup once a month. I don't trust the reliability of the seagate drives to stay on all the time.
