In the final instalment of this series, I’ll have a look at AFF setups that have about the same usable capacity, but are built out of different set of SSD drives. Both are using ADPv2 to maximize usable capacity.

This is also the point where things get little bit hairy.

In previous posts I was comparing apples to apples in hardware terms, the only difference was version of ADP used, solutions under comparison were equal in terms of total cost and performance.  Since ADPv2 is more efficient, you can lower $/GB without altering total cost or performance, making AFF more cost effiecient, you get more bang for your buck.

This time I am comparing apples to oranges in hardware terms. Using different hardware components makes comparison more complex, it is not just about usable capacity, different hardware has also different performance characteristics and total cost. I am not going to touch performance aspect too much as it would overcomplicate the comparison.
