Is RAID Relevant Anymore


i've spent last few days outlining how upgrade/replace external hard drives. 1 thing can't answer if need raid (1, 5, 10, etc) anymore. memory affordable, 'm thinking of doing away raid configurations , replacing them backups instead.

here proposed 4-bay enclosure configuration:
disk 1-2 (raid 0) yes, know said no more raids, disk 1-2 speed.
disk 3 (back of disk 1-2) automatically backs anytime adobe/phase 1 closes.
disk 4 (back of disk 3) automatically backs after each x day/week(s).

there separate backup of disk 4 runs on monthly basis , gets stored @ separate location.

can explain how running raid (1, 5, 10, etc) beneficial?

thank time.
 

lol. raid relevant still. raid fault tolerance not performance. @ risk of teaching suck eggs , apologise in advance if am... r means redundant - thats fault tolerant bit... :)
