the speed increases are the nice areas of RAID with raid 1, you can read really fast. i wonder if that's economical for mining read-speed-limited cryptocurrencies. with raid 0, you can write really fast because it's in parallel. _and_ you get tons of space. _but_, you don't get to read really fast. and you don't get redundancy, i think if your brain is working, there's a raid with a higher number that does both raid 1 and raid 0, so you can read fast, an duse a ton of disks to write fast, and you get failure redundancy. but_ you still don't get backups with raid, which means if a political enforcement group brainwashed you never to engage in forensics again, you'll have trouble recovering your data when you hit the writelimit of your flash.
