> which is better 8+2 or 8+1+spare?
8+2 is safer for the same speed
8+2 requires alittle more math, so its slower in theory. (unlikely seen)
(4+1)*2 is 2x faster, and in theory is less likely to have wasted space
in transaction group (unlikely seen)
(4+1)*2 is cheaper to upgrade in place because of its fewer elements
so, Mr (no scale on the time access) Elling: so what's the MTTDL
between theses three?
