Raid is 0 Stripping and has no bearing on the security (it's actually bad for data integrity but nothing on these would need back ups as it will be OS and games), it's more because benchmarks for storage cool.
Do you mean RAID 1? which would be redundancy where data is mirrored across 2...
Raid is more a meh might as well, I have a NAS and some spare SSDs for stuff I don't want to lose. Good shout on the warranty though!
They don't have these as custom loops so later I'll have to do that myself but that's the fun part :P
Ram was the main concern as I have not had an AMD CPU since...
