Why not use RAID10 so you have striped AND mirrored.

That should give you your performance and some security. (One can
always have more security!)

Haven't had any issue but a single drive failure (that I've just gotten a
replacement drive for and am working on its implementation into the array)
in three years. I've not had any issues with speed nor capacity.

(My array is 4 1TB drives.)

YMMV
