I built a machine recently with an 840 EVO 120GB as the C: drive, and now I'm out of room. I literally have, like, 1 GB left. So, since this is a rather high end machine, I'd like to know what the best option for me is: Just another, probably 250 GB SSD, or fast HDDs in RAID? I'd like to stay around $100-250 for whichever option I go for. I'm gaming and video editing. I'd like as much capacity for the above price point as possible.
My motherboard is the EVGA X79 Dark. It has support for RAID 0,1,5,10, and JBOD (though I don't know what JBOD is). If the RAID option is what I go with, I'd probably use the built-in RAID.
I might be able to get away with RAID 0 because I have a NAS I could back everything up on. I'm only editing personal videos, so losing hours/days of time after a disk fails to replace it can't be that big a problem, but I thought perhaps a RAID 5 array wouldn't hurt to have some internal redundancy.
