Striping raid is viable for 2 or 3 disks because of the redundancy. Software raid works fine for me. Hardware raid enables battery backed write behind but I don't know how important that is with ssds. Either way, we go 2xSSDs per server with os in mirrored raid and data striped.
Depending on your data you may want spinning disks instead, then battery backed writes are probably a bigger win.
